Calling Msys and MingW commands from outsite their environment (i.e. CreateProcess)
Date: 16/11/2014 Tags: mingw	So I wanted to check in on how Lgi apps built on Msys / MingW these days, particularly to have a look at implementing a GDB wrapper in the LgiIde application so that I can debug stuff directly in Linux without having to drop down to the command line. But never mind that convoluted explanation. The problem that I initially saw when trying to call Msys's 'make' was this: 0 [main] make.exe" 4408 fhandler_base::dup: dup(some disk file) failed, handle 0, Win32 error 6 /bin/sh: line 1: /c/Code/Lgi/trunk/LgiIde/C:/MinGW/msys/1.0/bin/make.exe: No such file or directory Then after I started using a different CreateProcess wrapper I got this: -f: Nothing to be done for `Makefile.windows'. I checked and re-checked that the path pointed to both the Msys and MingW bin directories in make's environment. But it still wouldn't work. From the command line it was fine, but doing a CreateProcess on make failed. It would appear that Msys make really needs to be run inside a shell of some sort. Even if it's just windows build in cmd.exe. So I ended up with code that looks like this: CreateProcess("C:\\Windows\\System32\\cmd.exe", "/C make.exe -f Makefile.windows", ...); Which works well enough for me.

So I wanted to check in on how Lgi apps built on Msys / MingW these days, particularly to have a look at implementing a GDB wrapper in the LgiIde application so that I can debug stuff directly in Linux without having to drop down to the command line. But never mind that convoluted explanation.

The problem that I initially saw when trying to call Msys's 'make' was this:

0 [main] make.exe" 4408 fhandler_base::dup: dup(some disk file) failed, handle 0, Win32 error 6
/bin/sh: line 1: /c/Code/Lgi/trunk/LgiIde/C:/MinGW/msys/1.0/bin/make.exe: No such file or directory

Then after I started using a different CreateProcess wrapper I got this:

-f: Nothing to be done for `Makefile.windows'.

I checked and re-checked that the path pointed to both the Msys and MingW bin directories in make's environment. But it still wouldn't work. From the command line it was fine, but doing a CreateProcess on make failed.

It would appear that Msys make really needs to be run inside a shell of some sort. Even if it's just windows build in cmd.exe. So I ended up with code that looks like this:

CreateProcess("C:\\Windows\\System32\\cmd.exe", "/C make.exe -f Makefile.windows", ...);
