           Summary: How to config gcc under AIX 4.2.1
           Product: gcc
           Version: 3.1.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: lq2001ca at yahoo dot ca
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: gcc 3.1.1
  GCC host triplet: AIX 4.2.1
GCC target triplet: c/c++

I built gcc 3.1.1 compiler under aix 4.3 successfully when I used following 
configuration:
../gcc-3.1.1/configure --prefix=/p/benjamin/usr/gcc-311-mlib-aixthread \
        --enable-languages=c,c++ \                                      
        --enable-threads=aix \                                          
        --disable-shared
My c++ multithreading program works properly. But My c++ multithreading program 
works properly, It gets core dump And I built gcc 3.1.1 under aix 4.2.1 
successfully wiht same configuration with aix 4.3. And I build my c++ 
multithreading program using -O2 -pthread -fexceptions -fstack-check 
compilation optione and -pthread link option. So I want to know correct 
configuration for gcc 3.1.1 compiler which support mulithtreading or 
compilation/link option under aix 4.2.1.  And I also found aix 4.2.1 missing 
pthread directory under lib(gcc 3.1.1) directory, aix 4.3 has this directory. 
So I wonder aix 4.2.1 need this directory or not or Maybe I'm missing some 
setting to build gcc 3.1.1 compiler. Any suggestion or help will be appreciated.

Thanks in advance.

Dave

First, 3.1.1 is no longer being updated and is almost a year old, can you try a newer gcc?

Second, we need more information, can you provide the preprocessed source files, read <http://
gcc.gnu.org/bugs.html> on how to get them?

Third, can you provide the back trace where you get the core dump?

I figureed out the reason why do we fail to build gcc 3.3 under aix 4.2.1. the 
reason is the Makefile is not correct for the target_srcdir = 
${glibcpp_srcdir}/config. because there is no the file ctype_base.h under the 
directory ${glibcpp_srcdir}/config. so target_srcdir should be set to 
${glibcpp_srcdir}/config/os/generic. I don't know why we run ./configure it 
doesnot generate correct Makefile. for temperary solution I just mannully 
modify Makefile like what I mentioned about. Now I successfully finished 
building gcc 3.3 under aix 4.2.1.
$ gcc -v

I can't figure out what you said about the Makefile/configury issue.  Could you try to explain it again, in clearer English and more detail?

Hi David,

Could you give me some explaination. does it mean under aix4.2 we can not 
compile multithreading program with GCC even if we have multithreading library? 
Thanks.

Hi Everyone,

I figured out to how to make GCC3.3 release for aix 4.2 to support pthread. 
Modify ./gcc-3.3/gcc/config.gcc file and create two new patch files

===========================================================================
1. The change of the ./gcc-3.3/gcc/config.gcc(new file is in attachment):
*** config.gcc             new
--- config.gcc             old

rs6000-ibm-aix3.2.[456789]* | powerpc-ibm-aix3.2.[456789]*)
	xm_defines=POSIX
	tm_file="${tm_file} rs6000/aix.h rs6000/aix3newas.h rs6000/xcoff.h"
	tmake_file=rs6000/t-newas
	use_collect2=yes
	extra_headers=
	;;

2208c2208
--- rs6000-ibm-aix4.[12]* | powerpc-ibm-aix4.[12]*)
*** rs6000-ibm-aix4.[1]* | powerpc-ibm-aix4.[1]*)                        
                                                                          
2213,2220d2212                                                         
*** rs6000-ibm-aix4.[2]* | powerpc-ibm-aix4.[2]*)                        
***       xm_defines=POSIX                                               
***       tm_file="${tm_file} rs6000/aix.h rs6000/aix42.h rs6000/xcoff.h"
***       tmake_file=rs6000/t-aix42                                      
***       use_collect2=yes                                               
***       thread_file='aix'
***       extra_headers=                                                 
***       ;;

2. The two new patch files are ./gcc-3.3/gcc/config/rs6000/aix42.h and ./gcc-
3.3/gcc/config/rs6000/t-aix42. they are in attachments.

After I built GCC3.3 with my changes I tested it with my c++ multithreading 
program it works properly. Could somebody help me to verify it and if it's 
correct please apply this patch to next release.

Thanks.
