One other thing to note - even though the compiler / linker complains about
these library incompatiblilties, the resulting a.out executes as expected on
a Solaris box.... wierd.

Subject: Skipping incompatable libaries on a SPARC cross compile
Hi All
I'm hoping one of the experts here can help me out with this problem...
I've built a Linux to Sun cross compiler using gcc-3.4.4. I've done this
before and had it work, but some problems have cropped up.... In the past
I've been able to build simple programs (ie - "Hello World") on linux and
execute them under Solaris on Sparc hardware, but it's quit working.
I'm using gcc-3.4.4 configured as follows:
cdl/apps/.software/linux/gcc-3.4.4-x86-sparc/sparc-sun-solaris2.9/bin/g++
-v
Reading specs from
/cdl/apps/.software/linux/gcc-3.4.4-x86-sparc/lib/gcc/sparc-sun-solaris2.9/3.4.4/specs
Configured with:
../gcc-3.4.4/configure --host=i686-pc-linux-gnu --target=sparc-sun-solaris2.9
--with-sysroot=/cdl/apps/.software/linux/gcc-3.4.4-x86-sparc-build/sysroot --with-gnu-as --with-gnu-ld --enable-languages=c,c++ --prefix=/cdl/apps/.software/linux/gcc-3.4.4-x86-sparc> Thread model: posix> gcc version 3.4.4> [EMAIL PROTECTED] helloworld]$>> The "sysroot" directory contains all of the goodies from /usr/lib,/usr/include, etc from a Sun box running Solaris 9. I can send a completefile list if anyone wants it I was really careful to make sure that all ofthe symlinks that were in these directories on the Sun machine werepreserved. When I try to build a simple hello world program:>> #include <stdio.h>> int main(void)> {> printf("Hello World!\n");> return 0;> }>> I get the following errors:>/cdl/apps/.software/linux/gcc-3.4.4-x86-sparc/lib/gcc/sparc-sun-solaris2.9/3.4.4/../../../../sparc-sun-solaris2.9/bin/ld: skipping incompatible/cdl/apps/.software/linux/gcc-3.4.4-x86-sparc-build/sysroot/lib/libm.so whensearching for -lm>/cdl/apps/.software/linux/gcc-3.4.4-x86-sparc/lib/gcc/sparc-sun-solaris2.9/3.4.4/../../../../sparc-sun-solaris2.9/bin/ld: skipping incompatible/cdl/apps/.software/linux/gcc-3.4.4-x86-sparc-build/sysroot/lib/libm.a whensearching for -lm>/cdl/apps/.software/linux/gcc-3.4.4-x86-sparc/lib/gcc/sparc-sun-solaris2.9/3.4.4/../../../../sparc-sun-solaris2.9/bin/ld: skipping incompatible/cdl/apps/.software/linux/gcc-3.4.4-x86-sparc-build/sysroot/lib/libc.so whensearching for -lc>/cdl/apps/.software/linux/gcc-3.4.4-x86-sparc/lib/gcc/sparc-sun-solaris2.9/3.4.4/../../../../sparc-sun-solaris2.9/bin/ld: skipping incompatible/cdl/apps/.software/linux/gcc-3.4.4-x86-sparc-build/sysroot/lib/libc.a whensearching for -lc>/cdl/apps/.software/linux/gcc-3.4.4-x86-sparc/lib/gcc/sparc-sun-solaris2.9/3.4.4/../../../../sparc-sun-solaris2.9/bin/ld: skipping incompatible/cdl/apps/.software/linux/gcc-3.4.4-x86-sparc-build/sysroot/lib/libc.so whensearching for -lc>/cdl/apps/.software/linux/gcc-3.4.4-x86-sparc/lib/gcc/sparc-sun-solaris2.9/3.4.4/../../../../sparc-sun-solaris2.9/bin/ld: skipping incompatible/cdl/apps/.software/linux/gcc-3.4.4-x86-sparc-build/sysroot/lib/libc.a whensearching for -lc>> (when compiling more complex examples I get a similar problem for -lrt)>> Can anyone shed some light on this? I've done some googling and turned upsome talk of 32 bit versus 64 bit architectures, but trying the build withan -m32 or -m64 made no difference. I've had this work before, so I'mprobably missing something obvious...>> Thanks> Mark>>> Mark Cuss, B.
