I'm trying to build a cross platform project for Ubuntu. In my makefile I have the line
"PSPSDK=$(shell psp-config --pspsdk-path)"
which gives the error "psp-config: Command not found."
psp-config is in my path and running make from the Ubuntu system on the files that get copied over from Visual Studio works fine. It also works if I manually ssh into the Ubuntu system from windows and run the command from there.
Why can't it find the command when run through Visual Studio?
You should update PATH at the beginning of "~/.bashrc" file (and not at the end) because it starts with somethign like:
# If not running interactively, don't do anything
case $- in
*i*) ;;
*) return;;
esac
Also, if you add code before these lines, it will be invoked for every subshell execution, so it is better to add a guard for it as well so it is invoked only once per session:
if [ -z $HOME_OPT_PATH_SET ]; then
export PATH=$PATH:$HOME/opt
export HOME_OPT_PATH_SET=1
fi
# If not running interactively, don't do anything
...

I am new to Lua programming language. I installed Lua for Windows v5.1.5-52. I want to use luacom library to run shell script. Here is my code,
local luacom = require('luacom');
local shell = luacom.CreateObject("WScript.Shell")
shell:Run ('echo 123', 0)
which throws the following error:
lua: COM exception:(.\src\library\tLuaCOM.cpp,398):The system cannot
find the file specified.
I looked for tLuaCOM.cpp file, but could not find it, not even folder src. Though I found luacom.dll in clibs folder.
Is there any workaround with this problem?
tLuaCOM.cpp is a luacom source file, so it's probably not on your PC, except you've build it yourself.
The error comes from one of the calls - either CreateObject() or Run.
The Run Method (Windows Script Host) helps says that it starts processes:
The Run method starts a program running in a new Windows process.
but echo is a shell command, not an executable, so you have to start an instance of the Windows command interpreter and pass your command like:
shell:Run('cmd /c "echo 123"')
My clone project path from github "C:\Users\Addy\Documents\polaris\"
I have created build directory "C:\Users\Addy\Documents\polaris\build"
From cmd.exe I access build directory path "C:\Users\Addy\Documents\polaris\build"
And run this command
"cmake -G "Visual Studio 10 Win64" -DCMAKE_CONFIGURATION_TYPES=Release;Debug .."
I am running this command on windows7 cmd. But it gives me the error.
**'cmake' is not recognised as an internal or external command**
As per the steps given in the
website(https://github.com/anl-polaris/polaris/wiki/Getting-Started)
It sounds like you don't have cmake in your path variables. Simple test, type 'echo %PATH%' in the command prompt, this will list all paths your OS will look for the executable in. If you can't see a path to your cmake executable then you need to add it.
Control Panel >> System >> Advanced System settings (left side on windows 10), too bring up the 'System Properties' window. In this window select 'Environmental Variables' to bring up a new window, then scroll down to PATH and enter the path to cmake.exe, click OK and close all windows to secure new settings.
On some versions of Windows this operation requires a restart before it takes affect, others you just need to open a new command prompt. I would start my opening a new command prompt and reentering 'echo %PATH%' command, looking for the new cmake path, if it's not here then restart Windows.
Its kinda an odd story. I'm trying to build the openssl library. Well, it is not the first time I'm doing it and until now it was fine. however, I've desided to add a build configuration to TeamCity (actually the problem has nothing to do with TeamCity)to build all my third parties libraries on-demand. So, I created a step with common set of openssl build commands:
perl Configure VC-WIN64A
ms\do_win64a.bat
nmake /d /f ms\ntdll.mak
... and the build failed while assembling the very first asm file. So I ran same commands in VS2012 x64 command prompt and the build succedeed, as expected. It took a while untill I figured out that the problem is in output redirection. Teamcity redirects output from build step to the teamcity build log, so did I by adding ">1.txt" to "nmake /d /f ms\ntdll.mak" command, and the build failed. I would say it is somewhat unexpected reason for build to fail.
So far, I've tried:
Building the same from VS2010 command prompt with redirection,
failed.
Building the same from VS2010 command prompt without
redirection, succeded.
Building the same from VS2010/VS2012 command
prompt with redirection to file and forcing redirection to CON (nmake
/d /f ms\ntdll.mak >CON >1.txt) failed.
Googling for "nmake problems
when console output is redirected" - nothing
Googling for "openssl
build problems when console output is redirected" - nothing
My setup
- Win2008R2, virtual machine.
- VS2010, latest updates
- VS2012, Update 1
Actual error:
NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\BIN\amd64\ml64.EXE"' : return code '0x1'
ml64.exe complains about the asm file stating it should end with "END" statement. It does, but...
Any ideas?
Ok, since the problem is in perl and writing files to stdout and then redirecting it you have to change following files to build x64 version:
crypto\aes\asm\aes-x86_64.pl
crypto\bn\asm\modexp512-x86_64.pl
crypto\bn\asm\x86_64-gf2m.pl
crypto\bn\asm\x86_64-mont.pl
crypto\bn\asm\x86_64-mont5.pl
crypto\md5\asm\md5-x86_64.pl
crypto\modes\asm\ghash-x86_64.pl
crypto\rc4\asm\rc4-md5-x86_64.pl
crypto\rc4\asm\rc4-x86_64.pl
crypto\sha\asm\sha1-x86_64.pl
crypto\sha\asm\sha512-x86_64.pl
crypto\whrlpool\asm\wp-x86_64.pl
crypto\x86_64cpuid.pl
engines\asm\e_padlock-x86_64.pl
you have to open these files and change all "open STDOUT "whateverfile"" to something like "open my $asmfile "whaeverfile"", then take care of string concatenation (only in x86_64cpuid.pl) and then print it to the file instead of STDOUT, something like "print $code" to "print $asm $code"
and of course, dont forget to close the file, in another words change the "close STDOUT" to "close $asmfile"
Obviously when building target other than x64 one will have to change another set of files.
Will try to communicate it to openssl maintainer.
I am using Windows 7 x32 and have already installed, sublime text 2, MinGW, also set PATH for minGW in system variables, but it still does not work.
I try to build it get [Finished in 0.8s] and then I try run, get this:
[Error 2] The system cannot find the file specified
[cmd: [u'bash', u'-c', u"g++ 'C:\\Users\\air\\Desktop\\test.cpp' -o 'C:\\Users\\air\\Desktop/cc' && 'C:\\Users\\air\\Desktop/test'"]]

It seems that because linux uses "/", but windows uses "\" in the file path. I try to change the "C++.sublime-build", but failed. I really don't know how to fix it, Can anybody help me?
I had the same problem and the answer came simple as 42: since bash needs to be run in cmd command, it must be in the path variable. In my case, bash was contained in MSYS (which can be installed optionally with MinGW), I added C:\MinGW\msys\1.0\bin to path, restarted Sublime Text and now run command is working.
I’ve produced a C++ program in Eclipse running on Redhat, which compiles and runs fine through Eclipse.
I thought that to run it separately to Eclipse you use the build artifact which is in the directory set via the project’s properties.
However this executable doesn’t run (I know it’s an executable as I’ve set it to be an executable via the project’s properties and it shows up as such via the ls command and the file explorer).
When attempting to run it using the executable’s name, I get the error:
bash: <filename>: command not found
When attempting to run it as a bash file:
<filename>: <filename>: cannot execute binary file
And when running it with "./" before the file name, nothing happens. Nothing new appears in the running processes and the terminal just goes to the next line as though I’d just pressed enter with no command.
Any help?
You've more or less figure out the first error yourself. when you just run <filename> , it is not in your PATH environment variable, so you get "command not found". You have to give a full or relative path when to the program in order to run it, even if you're in the same directory as the program - you run it with ./<filename>
When you do run your program, it appears to just exit as soon as you start it - we can't help much with that without knowing what the program does or see some code.
You can do some debugging, e.g. after the program just exits run echo $? to see if it exited with a particular exit value, or run your program using the strace tool to see what it does (or do it the usual way, insert printf debugging, or debug it with gdb)
