I am working on tesseract engine . Used red hat linux to build both leptonica and tesseract . On running tesseract getting following error.
[tesseract-ocr]$ tesseract address.png out1
Error in pixReadMemTiff: function not present
Error in pixReadMem: tiff: no pix returned
Error in pixaGenerateFontFromString: pix not made
Error in bmfCreate: font pixa not made
Tesseract Open Source OCR Engine v4.00.00alpha with Leptonica
Error in pixReadStreamPng: function not present
Error in pixReadStream: png: no pix returned
Error in pixRead: pix not read
Error during processing.
while searching on the net , i came to find that it is problem with leptonica build . and it is not built properly with ltiff . In fact in config.log which gets generated out of ./configure command . i can see following
configure:12538: checking for TIFFOpen in -ltiff
configure:12564: gcc -o conftest -g -O2 -Wl,-rpath -Wl,/lib64 conftest.c -ltiff -lm
>&5
/bin/ld: cannot find -ltiff
However i see that libtiff is present in the system
[ec2-user#ip-172-31-35-131 lib]$ ldconfig -p | grep libtif
libtiffxx.so.5 (libc6,x86-64) => /lib64/libtiffxx.so.5
libtiff.so.5 (libc6,x86-64) => /lib64/libtiff.so.5
I tried pointing to /lib64 path , as per reference from leptonica site [http://www.leptonica.com/source/README.html][1]
Finally, if you find that the installed programs are unable to link
at runtime to the installed library, which is in /usr/local/lib,
try to run configure in this way:
LDFLAGS="-Wl,-rpath -Wl,/usr/local/lib" ./configure
which causes the compiler to pass those options through to the linker.
changing LDFLAGS to point to /lib64 is also not working LDFLAGS="-Wl,-rpath -Wl,/lib64" ./configure
Any suggestions ?
Try to install
apt-get install -y libtiff5-dev
Then install leptonica from source
git clone https://github.com/DanBloomberg/leptonica.git leptonica
cd leptonica
./autobuild
./configure --with-libtiff
make -j
make install
And reinstall tesseract after that

I've been trying to convert a cpp file to wasm without emscripten recently and I've been running with some errors, for example, when I run these commands:
clang++ --target=wasm32 -nostdlib -O3 -o public/main.o -c src/*.cpp
wasm-ld --no-entry --export-all --lto-O3 --allow-undefined --import-memory public/main.o -o public/main.wasm
it gives me this error:
wasm-ld: error: unknown file type public/main.o
Here are the versions of clang and lld that I currently have:
clang version 12.0.1
Target: x86_64-unknown-linux-gnu
Thread model: posix
InstalledDir: /nix/store/jp4r5v8pla63qam5w34jvfyfmq8p74am-clang-12.0.1/bin
LLD 12.0.1
Also, I'm running the code on replit
Thank you
Ok, with this commands it works :D
clang++ --target=wasm32 -emit-llvm -c -S -o public/files/main.ll src/main.cpp
llc -march=wasm32 -filetype=obj -o public/files/main.o public/files/main.ll
wasm-ld --no-entry --export-all -o public/main.wasm public/files/main.o
The only thing is that you need to create some new files (main.ll and main.o) but it doesn't matter.

I'm trying to install CUDA 7.0 on Ubuntu 14.04. I've followed the installation instructions as outlined here. Specifically, I've followed steps in section 3.6 and Chapter 6. While compiling the examples (Section 6.2.2.2) using make, I'm getting the following error:
make[1]: Entering directory `/usr/local/cuda-7.0/samples/3_Imaging/cudaDecodeGL'
/usr/local/cuda-7.0/bin/nvcc -ccbin g++ -m64 -gencode arch=compute_20,

/usr/bin/ld: cannot find -lnvcuvid
collect2: error: ld returned 1 exit status
make[1]: *** [cudaDecodeGL] Error 1
make[1]: Leaving directory `/usr/local/cuda-7.0/samples/3_Imaging/cudaDecodeGL'
make: *** [3_Imaging/cudaDecodeGL/Makefile.ph_build] Error 2
If you notice, there is -L/usr/lib/"nvidia-346". In my case, I have installed nvidia-349. What worked for me is to edit NVIDIA_CUDA-7.0_Samples/3_Imaging/cudaDecodeGL/findgllib.mk and change UBUNTU_PKG_NAME = "nvidia-346" to nvidia-349.
In order to properly install CUDA 7.0 on Ubuntu 14.04, you need a nvidia driver version 346 or higher.
If you're using the .deb installation method, the nvidia graphics driver is installed automatically.
If you used the .run file installation method and chose not to install the nvidia driver, you can manually install the driver afterwards through the package manager:
sudo apt-add-repository ppa:xorg-edgers/ppa && sudo apt-get update
sudo apt-get install nvidia-346 nvidia-346-dev nvidia-346-uvm libcuda1-346 nvidia-libopencl1-346 nvidia-icd-346
In my case, I installed nvidia-352 afterwards due to a bug in nvidia-346 and I stumbled upon the same error.
andoum's approach of manually changing the hard-coded UBUNTU_PKG_NAME = "nvidia-346" to UBUNTU_PKG_NAME = "nvidia-352" in NVIDIA_CUDA-7.0_Samples/3_Imaging/cudaDecodeGL/findgllib.mk worked fine for me.
I met the same issue and solution is that put path of nvidia into system path:
sudo gedit /etc/environment
add these path into environment
LIBRARY_PATH=/usr/lib/your_nvidia_edition:$LIBRARY_PATH
In fact I have encountered this problem when I made a make. I installed Cuda 8.0 under my Ubuntu 16.04. This problem had been confusing me for several weeks and I was almost tending to reinstall ubuntu for that after reviewing many suggestions via google, but finally I addressed it myself recently.
First of all, you should replace all the UBUNTU_PKG_NAME= ##nvidia-3xx## to the one of your actually installed nvidia driver version as recommended above. Then you will probably get compiling error after you do a new make. In my case, I have the link errors like
/usr/bin/ld: warning: libGLX.so.0, needed by /usr/lib/nvidia-
375/libGL.so, not found (try using -rpath or -rpath-link)
/usr/bin/ld: warning: libGLdispatch.so.0, needed by /usr/lib/nvidia-
375/libGL.so, not found (try using -rpath or -rpath-link)
....
or whatever contains missing link errors. Do locate the files you miss like
$ locate libGLX.so.
/usr/lib/nvidia-375/libGLX.so.0
/usr/lib32/nvidia-375/libGLX.so.0
$ locate libGLdispatch.so.0
/usr/lib/nvidia-375/libGLdispatch.so.0
/usr/lib32/nvidia-375/libGLdispatch.so.0
The error above is probably caused the compiling files cannot find in the default cuda libraries as you set, so you just need to copy the missing files to /usr/lib/nvidia-3xx/ (the actual path in your case) and this should work(it works in my case), if it doesn't maybe you could try to link the new add files to the one that need using a
$ sudo ln -s (requested file) (requesting file).
Hope this will help.
I have this problem with freeradius module.
I'm trying to add my custom module, but after I launch radius server in debug mode it shows me this error:
/usr/local/etc/raddb/modules/m2[2]: Failed to link to module 'rlm_m2': libmysql.so.16: cannot open shared object file: No such file or directory
/usr/local/etc/raddb/sites-enabled/default[224]: Failed to load module "m2".
/usr/local/etc/raddb/sites-enabled/default[69]: Errors parsing authorize section.
My system is Ubuntu 12, all mysql packages are installed correctly(there does exist libmysql.so.16 in usr/lib/mysql) freeradius runs smoothly with default parameters and so on. I really don't have an idea what exactly can't find this mysql library or how to show it to it.
Try compile like this:
gcc -I/usr/include/mysql rlm_m2.c -o rlm_m2 -lmysqlclient -lnsl -lm -lz\
-L/usr/lib/mysql -L/usr/lib/mysql -L/usr/lib64/mysql
i installed sabayon linux and i tried to install pycuda but i am receiving the following error when i try
su -c "make install"
In file included from src/cpp/cuda.cpp:1:0: src/cpp/cuda.hpp:12:18:
fatal error: cuda.h: No such file or directory compilation terminated.
error: command 'x86_64-pc-linux-gnu-g++' failed with exit status 1
I must mention that i can compile with cuda.
The same happens and when i try with
sudo -E sh -c "make install"
My .bashrc is :
# Put your fun stuff here.
export PATH=~/bin:$PATH
export PATH=$PATH:$HOME/Matlab_2010b/bin
export PATH=/opt/cuda/bin:$PATH
export LD_LIBRARY_PATH=/opt/cuda/lib64:$LD_LIBRARY_PATH
export CUDA_ROOT=/opt/cuda/bin
(When i do echo $PATH as user it shows me : /opt/cuda/bin but when i try it as root it doesn't show anything and i had to do export PATH...again in order to show.)
You have CUDA installed in a non-standard path and the PyCUDA installer doesn't know how to find the toolkit headers it needs to compile. As per the installation instructions, you need to do something like this:
python configure.py --cuda-root=/opt/cuda
then
su -c "make install"
this will ensure that the compilation can find the necessary driver API headers to build the support libraries and hardcode all the right paths into the PyCUDA python libraries so that everything works correctly.
I'm attempting to get DBD::MySQL working on Snow Leopard (v10.6.6). The default version of Perl that comes with the OS is v5.10.0. Since I've read that's 64-bit, I went ahead and downloaded and installed a 64-bit version of MySQL (mysql-5.5.8-osx10.6-x86_64).
Installing and setting up MySQL went smoothly, here's my config and version number for reference.
I used CPAN to download DBI and the DBD::MySQL drivers. I then:
Installed DBI
Setup a Makefile.PL
Ran the make command from the command line
The Makefile.PL said it would use the following settings for compiling and testing:

Everything seemed to be going fine, until I tried to run make test :

It's failing because it can't seem to find the mysql.bundle for DBD. Has anyone come across this problem? Or can point me in the right direction on what to try next? I need DBI/DBD::MySQL for my new job and I'm scrambling to find a solution.
Many thanks in advance.
I got around the "Library not loaded: libmysqlclient.16.dylib" problem by placing a symbolic link in /usr/lib/" to /usr/local/mysql-5.5.8-osx10.6-x86_64/lib/libmysqlclient.16.dylib
I worked around the same or a similar issue. Somehow I could build and test DBD::mysql with cpan but when I tried to use it in a script it said things like
dyld: lazy symbol binding failed: Symbol not found: _mysql_init
Referenced from: /Library/Perl/5.10.0/darwin-thread-multi-2level/auto/DBD/mysql/mysql.bundle
Expected in: flat namespace
Apparently, it's a 64-bit vs 32-bit issue.
Installing the fink dbd-mysql-pm5100 package made it work though it took kind of a long time. I also removed the cpan-installed version:
sudo rm -rf /Library/Perl/5.10.0/darwin-thread-multi-2level/auto/DBD/mysql
sudo rm -rf /Library/Perl/5.10.0/darwin-thread-multi-2level/DBD/mysql
sudo rm -rf /Library/Perl/5.10.0/darwin-thread-multi-2level/DBD/mysql.pm
also include in .profile
export VERSIONER_PERL_PREFER_32_BIT=yes;
Besides creating the link the executions of the program with DBI::mysql generated an error, thus including this variable on the environment make it works
I know this is an old post. But I suppose the best solution would be to add the library directory to the DYLD_FALLBACK_LIBRARY_PATH env variable. (reason here: https://stackoverflow.com/a/3172515/119958 )
There is no ldconfig in mac, so just add the path to this env var and rerun the install process for DBD::mysql

Donato's solution works for install, but the var has to be present at runtime as well or I get the same error. The following fixes this at runtime for shell and _www user:
# For command line use, add following line to ~/.bash_profile:
export DYLD_FALLBACK_LIBRARY_PATH=/usr/local/mysql/lib/:$DYLD_FALLBACK_LIBRARY_PATH
# If Apache needs it, add following line to /etc/apache2/httpd.conf:
# On Lion Server, I put it after <IfDefine MACOSXSERVER>, but shouldn't matter
SetEnv DYLD_FALLBACK_LIBRARY_PATH /usr/local/mysql/lib/:$DYLD_FALLBACK_LIBRARY_PATH
It's somewhat of an aside, but I strongly recommend setting up a separate perl on the machine -- either by fink / macports, or from source -- and leaving the Mac's system perl (and its libraries) alone.
Once I did this on my own Mac, I had very few troubles installing modules thereafter, and I didn't have to worry about accidentally blowing a hole in my OS by breaking the perl that the system uses.
If it were my Mac, I'd install a new perl from source (the Perl source distribution is smart enough to install itself see that it's on a Mac and install itself safely into /usr/local/bin) and the proceed from thee to install DBD::Mysql (and the other modules you require).
