Can't find values-Xa.o when cross compiling

Can't find values-Xa.o when cross compiling

[Mark Cuss]

 Hello All

I've built gcc-3.4.4 as a linux to Solaris (on SPARC) cross compiler.  If I
change my path to include my new compiler executables, I can compile and
 link a simple "hello world" program.

 However, I want to be able to specify the target architecture and compiler
 version number with gcc's -b and -V flags.  When I try to build my program
 using these flags, the system can't find values-Xa.o:
 [mark@locutus helloworld]$ g++ -b sparc-sun-solaris2.9 -V 3.4.4 hello.cxx
 /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: values-Xa.o: No such file: No such file or directory collect2: ld returned 1 exit status [mark@locutus helloworld]$ The file is in $sysroot/usr/lib (and $sysroot/usr/ccs/lib too).  $sysroot was set as configure option when built gcc.  According to the docs, itlooks like $sysroot should be searched for the library & object files, but it doesn't seem to work.  Even if I specify the path to the linker with -Wl,-L <path>, it still can't find the file.  However, if I directly call gcc instead of using -b and -V to call sparc-sun-solaris2.9-gcc, it works... Any ideas why this might be?

Hello all

Can anyone shed any light on this problem for me?  I've built gcc 3.4.4 as a 
Linux (on x86) to Solaris (on SPARC) cross compiler.  When I do the make 
install, I get 2 sets of binaries:

1)  $prefix/bin - this contains all of the binaries with 
'sparc-sun-solaris2.9' in front of them (ie - sparc-sun-solaris2.9-g++, etc)
2)  $prefix/sparc-sun-solaris2.9/bin - this contains all of the binaries 
with their normal names (ie - g++, gcc, etc)

If I set my PATH to $prefix/sparc-sun-solaris2.9/bin, then I can build a 
simple "hello world" test program.  However, if I either directly call 
$prefix/bin/sparc-sun-solaris2.9/g++ or indirectly call it by using g++ -b 
sparc-sun-solaris2.9, I get:

[mark@locutus helloworldsun]$ g++ -b sparc-sun-solaris2.9 hello.cxx
/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: 
values-Xa.o: No such file: No such file or directory
collect2: ld returned 1 exit status
[mark@locutus helloworldsun]$

values-Xa.o lives in $sysroot/usr/ccs/lib like it's supposed to.  If I call 
$prefix/sparc-sun-solaris2.9/bin/g++ it finds it OK, but 
$prefix/bin/sparc-sun-solaris-2.9-g++ can't - any ideas why this might be? 
I've tried including the path to values-Xa.o with -L but that hasn't helped? 
I'd really appreciate some pointers on this one.

Thanks in advance

Mark

Building cross compilers for solaris is not common, so it may be that no 
one else has seen this problem.  You may have to try to figure this out 
yourself.  Or you could try submitting a bugzilla bug report and hope 
that someone looks at this.

/usr/ccs/lib is not a normal search directory for gcc, so it may be that 
the mechanism we use for it doesn't work for crosses.  Checking, I see 
that config/svr4.h doesn't set MD_STARTFILE_PREFIX when CROSS_COMPILE is 
true.  Also, the driver, gcc.c, does not use MD_STARTFILE_PREFIX when 
CROSS_COMPILE is true.  This might need some work to fix.  Though this 
doesn't explain why it does work for one of your compilers but not the 
other.

Try adding verbose options to see what is happening, i.e. compile with 
-v -Wl,-v and look at the output to see if you can see something that 
explains what is happening.

This is a very old patch I used to build a Solaris cross compiler on
Linux.
