I am trying to get a value from an instance with OID using tcl command.
In TCL, the command works:
% set snmp_result [snmpwalk -Os -c public -v 2c 192.168.1.20 .1.3.6.1.4.1.31926.2.1.1.19]
iso.3.6.1.4.1.31926.2.1.1.19.1 = INTEGER: -57
I am trying to get the number -57 only, so I wrote a tclsh script:
set snmp_result [snmpwalk -Os -c public -v 2c 192.168.1.20 .1.3.6.1.4.1.31926.2.1.1.19]
set splitted_result [split $snmp_result ""]
puts [lindex $splitted_result 3]
And then I got error:
invalid command name "snmpwalk"
while executing
"snmpwalk -Os -c public -v 2c 192.168.1.20 .1.3.6.1.4.1.31926.2.1.1.19"
invoked from within
"array set snmp_result [snmpwalk -Os -c public -v 2c 192.168.1.20 .1.3.6.1.4.1.31926.2.1.1.19]"
(file "./siklu.tcl" line 1)
I also learned that the tclsh is EEM policy, so I tried:
array set snmp_res [sys_reqinfo_snmp -c public -v 2c 192.168.1.20 oid .1.3.6.1.4.1.31926.2.1.1.19 get_type exact]
But that gave me this error:
invalid command name "sys_reqinfo_snmp"
while executing
"sys_reqinfo_snmp -c public -v 2c 192.168.1.20 oid .1.3.6.1.4.1.31926.2.1.1.19 get_type exact"
invoked from within
"array set snmp_res [sys_reqinfo_snmp -c public -v 2c 192.168.1.20 oid .1.3.6.1.4.1.31926.2.1.1.19 get_type axact]"
(file "./siklu.tcl" line 2)
You have to use exec command to execute them.
set snmp_result [exec snmpwalk -Os -c public -v 2c 192.168.1.20 .1.3.6.1.4.1.31926.2.1.1.19]
puts $snmp_result

It builds fine on Windows MSVC, Macos Clang, Linux GCC, but fails using Mingw GCC, here is error shown:

Build works fine without building gtest, and it fails when building test executable with gtest
When I running jq command locally it works:
jq --arg ip "$IP" '.nodes|.app|.ip = $ip' nodes.json
Output:
{
"nodes": 1,
"is_manager": true,
"ip": "127.0.0.1",
"cpus": 16,
"memory": 64
}
But I can't figure out how do I send it remotely via ssh, for example this command returns an error:
ssh -o StrictHostKeyChecking=no -i key.pem user#"172.13.1.23" "jq --arg ip "127.0.0.1" '.nodes|.app|.ip = $ip' nodes.json"
Output:
jq: error: syntax error, unexpected $end (Unix shell quoting issues?) at , line 1:
.nodes|.app|.ip =
jq: 1 compile error
$ip is in double quotes, and so is expanded locally. You need to escape the dollar sign.
ssh -o StrictHostKeyChecking=no -i key.pem user#"172.13.1.23" \
"jq --arg ip "127.0.0.1" '.nodes|.app|.ip = \$ip' nodes.json"
My environment is Ubuntu15.10.
I wrote the following source code.
#include "efi.h"
#include "efilib.h"
EFI_STATUS
EFIAPI
efi_main(EFI_HANDLE ImageHandle, EFI_SYSTEM_TABLE *SystemTable)
{
InitializeLib(ImageHandle, SystemTable);
Print(L"HelloWorld\n");
return EFI_SUCCESS;
}
I wrote the following Makefile and compile source code.
ARCH = $(shell uname -m | sed s,i[3456789]86,ia32,)
OBJS = main.o
TARGET = hello.efi
EFIINC = /usr/include/efi
EFIINCS = -I$(EFIINC) -I$(EFIINC)/$(ARCH) -I$(EFIINC)/protocol
EFILIB = /usr/lib
EFI_CRT_OBJS = $(EFILIB)/crt0-efi-$(ARCH).o
EFI_LDS = $(EFILIB)/elf_$(ARCH)_efi.lds
CFLAGS = $(EFIINCS) -fno-stack-protector -fpic \
-fshort-wchar -mno-red-zone -Wall
ifeq ($(ARCH),x86_64)
CFLAGS += -DEFI_FUNCTION_WRAPPER
endif
LDFLAGS = -nostdlib -znocombreloc -T $(EFI_LDS) -shared \
-Bsymbolic -L $(EFILIB) -L $(LIB) $(EFI_CRT_OBJS)
all: $(TARGET)
hello.so:$(OBJS)
ld $(LDFLAGS) $(OBJS) -o $# -lefi -lgnuefi
%.efi: %.so
objcopy -j .text -j .sdata -j .data -j .dynamic \
-j .dynsym -j .rel -j .rela -j .reloc \
--target=efi-app-$(ARCH) $^ $#
I store hello.efi on named RT directory and I run "qemu-system-x86_64 -bios OVMF.fd -hda fat:RT/".
I run hello.efi but not execute my UEFI application.
Qemu say "Error reported: Invalud Parameter".
Please help me!
Removing -L $(LIB) from the LDFLAGS in the Makefile helped:
Don't you need 'main()' vs. 'efi_main()'?
I'm trying to build fiware-IoTAgent-Cplusplus from source but I am getting strict-aliasing error. Any idea?
The commands I used to perform the build are as follows.
Note that I am building inside a lxc using CentOS 6.7.

I got it. I was using a 32 bit CentOS.
I've been trying to install IDAS GE in a CentOS 7 VM on my machine through the UL2.0 RPMs(download link!) available in its catalogue page.
I followed the instructions on github, but I get stuck in starting the IoT as per section 3 of the Deployment section of the instructions. If I execute the init_iotagent.sh, where I inserted the local IP of the VM, I get the error:
log4cplus:ERROR No appenders could be found for logger (main).
log4cplus:ERROR Please initialize the log4cplus system properly.
HTTPFilter DESTRUCTOR 0
HTTPFilter DESTRUCTOR 0
Also, in the instructions for Starting IoTAgent as a Service, it's said that:
After installing iot-agent-base RPM an init.d script can be found in
this folder /usr/local/iot/init.d .
But this file is not there, leading me to believe that the IoTAgent wasn't installed properly from the RPMs provided.
Also, I can't find log files regarding IoTAgent, only the MongoDB has its log file at /usr/local/iot/mongodb-linux-x86_64-2.6.9/log/mongoc.log.
If anyone could help, it would be apreciated. Also, if more info is needed, please let me know.
Thank you
I recommend you to get the GitHub repository and build the RPMs from the source and then install it in your CentOS. Like is explained in the documentation:
NOTE: I changed the BUILD_TYPE to Release, so I created the Release dir.
GIT_VERSION and GIT_COMMIT are not the latest ones.
git clone https://github.com/telefonicaid/fiware-IoTAgent-Cplusplus.git
cd fiware....
mkdir -p build/Release
cd build/Release
cmake -DGIT_VERSION=20527 -DGIT_COMMIT=217023407f25ed258043cfc00a46b6c05fb0b52c -DMQTT=ON -DCMAKE_BUILD_TYPE=Release ../../
make install
make package
The packages will be in pack/Linux/RPM/
rpm -i iot-agent-base-xxxxxxx (xxxxxxx will be the numbers of the build)
rpm -i iot-agent-ul-xxxxxx (xxxxxxx will be the numbers of the build)
Once installed with RPMs the init.d file is in: /usr/local/iot/init.d/iotagent
