Re: [Mingw-users] Building libstdc++ SVN trunk with MinGW

[François D. <fra...@fr...>]

Hi

I am sorry to insist on this point but I really think that a good 
localization support would be a great enhancement for MinGW. So here are 
the last lines I have when I run make to build the complete gcc package 
for C and C++ language using the configure command advised in this thread:

      No need to remake target `cpp.exe'.
      Considering target file `specs'.
       File `specs' does not exist.
        Pruning file `xgcc.exe'.
       Finished prerequisites of target file `specs'.
      Must remake target `specs'.

Putting child 0x00fb37f8 (specs) PID 16505408 on the chain.
Live child 0x00fb37f8 (specs) PID 16505408
/usr/bin/sh: c: command not found

/usr/bin/sh: C:Utilsmsys1.0Utilsgcc-buildgcc -Lc: command not found

The build script is generating a really weird command. I guess there 
must be some trouble with management of '/' or '\' or with the C: 
problem exposed in this thread too. Do you know how I
can debug this problem ?

Thanks
