Re: subdir-objects with FORTRAN and location of objects

[Federico Carminati]

Hello,
  thanks for the answers. gcc fortran compilers support -o -c,  
however without the AM_PROG_F*_C_O the .o files are produced in the  
build directory and not in the subdirectory. AC_PROG_F*_C_O is not  
enough to guarantee this. I am using libtool  1.5.8 on Darwin 8.2.0  
powerpc. Best regards
