Re: Building a Solaris cross compiler


That made the configure work and the build goes part way, but it ends up
stopping on:

/users/mark/cross2/build-gcc/gcc/xgcc -B/users/mark/cross2/build-gcc/gcc/ -B
/users/mark/cross2/build-install/sparc-sun-solaris2.9/bin/ -B/users/mark/cro

../../gcc-3.4.0/gcc/config/sparc/gmon-sol2.c: In function `_mcleanup':
../../gcc-3.4.0/gcc/config/sparc/gmon-sol2.c:182: error: `PATH_MAX'
undeclared (first use in this function)
../../gcc-3.4.0/gcc/config/sparc/gmon-sol2.c:182: error: (Each undeclared

make[1]: *** [gmon.o] Error 1
make[1]: Leaving directory `/users/mark/cross2/build-gcc/gcc'
make: *** [all-gcc] Error 2

I did a google for this and read that if one includes limits.h in the
gmon-sol2.c file that the problem goes away, but I tried this and had the
same problem.  I think the problem is because there is a limits.h in the
Solaris headers (in which PATH_MAX defined), but there is also 2 limits.h
files in the gcc source tree.  I'm thinking that the compiler picks up the
limits.h from the gcc tree and ignores the one in the Solaris headers
causing the error to occur.

Has anyone seen this before?  Does anyone know which limits.h file I should
be using?

Thanks in advance,
