Following this tutorial at chapter 6 I tried to create my first own project.
I create my directory "first" with two files: build.sbt and first.scala ( exactly as described by the tutorial, I just used another name, "first" for my project instead of "hello" ).
But, when I type the following comand:
sbt run --backend c
I have this error:
[error] Not a valid command: backend (similar: append)
[error] backend
[error] ^
What's wrong?
Thank you in advance.
Francesco
the arguments with run need to be surrounded with quotes:
sbt "run --backend c"
(tutorials have been updated to reflect the proper use)

I am using JDK: 1.8.0.281 and Drill: 1.18.0 on m1 Mac.
I cannot start drill downloaded from https://drill.apache.org/download/ directly. It says
could not find or load main class sqlline.sqlline. So I refer to https://github.com/julianhyde/sqlline/issues/69, download and compile sqlline and add these two lines
BINPATH=/Users/fields/Repositories/sqlline-sqlline-1.9.0/bin
exec java -cp $BINPATH/../target/sqlline-1.9.0-jar-with-dependencies.jar sqlline.SqlLine "$#"
to the beginning of drill/bin/sqlline. Then I start drill-embedded and get no current connection every time I enter a query.
Please help me identify the problem. Thanks a lot!!!
I'm trying to train the Tesseract4.0 following the steps in the tutorial:
https://github.com/tesseract-ocr/tesseract/wiki/TrainingTesseract-4.00---Replacing-Top-Layer-Example
But when I execute the command:
mkdir -p ~/tesstutorial/nor_layer
$ combine_tessdata -e ../tessdata/nor.traineddata ~/tesstutorial/nor_layer/nor.lstm
An error message is given by the system, which is shown as following: Not extracting /home/robert/tesstutorial/nor_layer/nor.lstm, since this component is not present.
Why do I receive this error? The message in the tutorial shows: "Wrote /home/shree/tesstutorial/nor_layer/nor.lstm" represents nor.lstm will be written.
But why the system hint the nor.lstm file not present? Can you help me... (Thanks)
It is because you are most probably using tessdata from version 3. You have to use tessdata from the tessdata_best repository on Github.
I've installed latest sphinx version 2.3.1.
I have TYPO3 CMS 6.2.19.
Before sphinx can be used it must be configured. Now in sphinx configuration area I click on Sphinx 1.4.5. After some time I get following message:
Sphinx 1.4.5 has been downloaded.
Could not extract Sphinx 1.4.5:
Could not extract 3rd-party libraries for Sphinx:
Archive: /opt/lampp/htdocs/cms1/typo3temp/sphinx-contrib.zip
Inconsistency detected by ld.so: dl-open.c: 596: _dl_open: Assertion `_dl_debug_initialize (0, args.nsid)->r_state == RT_CONSISTENT' failed!
Could not find a compatible version of Pygments
I could debug this extension and found out it crashes at following command:
CommandUtility::exec("'/usr/bin/unzip' '/opt/lampp/htdocs/cms1/typo3temp/sphinx-contrib.zip' -d '/opt/lampp/htdocs/cms1/uploads/tx_sphinx/sphinx-contrib' 2>&1", $out, $returnValue);
If I execute it from a php-one-line script I get following message:
lchmod (file attributes) error: Function not implemented
Does anybody understand what is wrong with it???
OK. I've found a workaround myself: it were libraries. So I had to preload another versions.
All in all, the way is: in the file where unzip is called (Setup.php) in the function unarchive add LD_PRELOAD=/lib64/libgcc_s.so.1:/usr/lib64/libstdc++.so.6 before unzip command. Now it looks as follows:
$cmd = 'LD_PRELOAD=/lib64/libgcc_s.so.1:/usr/lib64/libstdc++.so.6 ' . $unzip . ' ' . escapeshellarg($archiveFileName) ...
And yes, it is not the best solution, but it worked for me.
I am using ofbiz in my organization. I want to migrate ofbiz from derby to MySQL.
I refer the steps from

At the end when I type (java -jar ofbiz.jar -install) this command I am getting an exception,
C:\Users\sagar_vinod_khanke\Sagar\Apache OFBiz\Ofbiz\13.07>java -jar ofbiz.jar -

don't use - with install.
See revised Step-V
Step-V
1. Run the following command from command prompt:
java -jar ofbiz.jar install
2. Start OfBiz

b. Go to Applications>WebTools
c. Go to section 'Entity XML Tools' and click the link 'XML Data Import Dir' -> In the 'Absolute directory path:' enter the full path of the directory where you exported the data in Step - II
I want to build libmysql.dll, so I got source code mysql-connector-c-6.1.6-src.zip from http://dev.mysql.com/downloads/connector/c/.
Then cmake-gui.exe to configure and generate vc 2008 sln, leave all settings default.
Then got errors and warnings when building, like this:
mysql-connector-c-6.1.6-src\include\thr_cond.h(109) : error C2065: “ETIMEDOUT”: 未声明的标识符(an unspecified identifier)
mysql-connector-c-6.1.6-src\include\thr_rwlock.h(80) : warning C4013: “TryAcquireSRWLockShared” 未定义(not defined)
mysql-connector-c-6.1.6-src\include\thr_rwlock.h(102) : warning C4013: “TryAcquireSRWLockExclusive” 未定义(not defined)
I searched the source, and find ETIMEDOUT is defined in my_pthread.h, so I include this header in thr_cond.h, but still error.
And TryAcquireSRWLockShared and TryAcquireSRWLockExclusive seem only supported on Win7 and later !
Do I have done something wrong?
How can I build libmysql?
Any help will be appreciated.
Download the previous version (6.0.2), it doesn's use the TryAcquireSRWLockShared() API function.
With a few minor tweeks, it compiles clean with MSVC 2008.
Here are the modifications (based on the extracted zip file root):
Replace line 306 of include/config-win.h with:
// avoid annoying warning
#ifndef HAVE_COMPRESS
# define HAVE_COMPRESS
#endif
Comment lines 350-367 of CMakeLists.txt (CPack instructions cause CMake to fail)
