Greetings,

On one of our old IBM SP nodes (Uniprocessor), I have installed gcc.2.95.2.tar file...

We are running AIX 4.2.1 (I know, old)...and the error i am getting when I am compiling a program via:

gcc -DNOUNDERSCORE -DMPI -o ../parseconfig ./parseconfig.c

is the following:

cpp: installation problem, cannot exec `cpp': Arg list too long
make: The error code from the last command is 1.


Stop.

gcc appears to be working, but the call to "cpp" is fouling it up.


FYI:

which gcc gives: /usr/local/bin/gcc (where the tar file extracted it to)
and: which cpp gives: /usr/local/bin/cpp (where the tar file extracted it to)

I can not move further with this project until this is figured out!!! Someone pleeeease help!

Greetings...the error listed above has been somewhat remedied...but a different error has erupted...

Here's the setup:

AIX 4.2.1 - gcc-2.95.2

To configure and build I:

configure
make bootstrap-lean
make install

All three of these commands ran and did not kick up ANY errors.

I have a test C-program in my home directory:

#include <stdio.h>

main()
{
printf("Hello.\n");
}


When i type:

gcc test.c

I get the following error:

$ gcc test.c
test.c:0: /usr/local/lib/gcc-lib/rs6000-ibm-aix4.2.1.0/2.95.2/../../../../rs6000-ibm-aix4.2.1.0/include/.: Permission denied

What is even MORE troubling is that this pgm compiles (in the same and other directories) and runs PERFECTLY while compiled and run as ROOT.

This seems like a permissions error...can someone help me out?!?!??!?!?!

So what are the permissions on the that file and others involved?

I would say that it's a very good sign that your program compiles as root but not as a non-root user. It's a good indication that your problem is a file permissions issue, easily fixed once you find it, rather than something more fundamental not working.

When you check permissions, remember to check the parent directories (up to /) as well as the files : if a directory has no "other" permissions at all and you're not the owner or a group member, then you won't be able to access files underneath it.

Being on 4.2.1 is a problem - I assume you can't easily upgrade. If you were on AIX 5 I'd suggest using truss to show you which files were being accessed by the command; but on 4.2.1 you're a lot more limited.

ianir...yes you were right...i found a directory that: gcc was trying to access and the permissions were the stopper...thanks for the help.

i too was looking for a "trace/truss" command on aix 4.2.1....is there one on any versions in the 4.3 era??? or just aix 5 and above?

thanks again!
