Summary: compile problem on hpux11.23. Urgent!

Initial Comment:
My server is: HP Integrity rx2620 hpux11.23.

I want to compile one source which needs to link libexpat.a on hpux. The message always as following:
ld: Can't find library or mismatched ABI for -lexpat
Fatal error.
*** Error exit code 1

Stop.
*** Error exit code 1

Stop.
*** Error exit code 1

I downloaded a version from http://hpux.cs.utah.edu/ which was special for hpux11.23. After installing expat, I copied the libexpated to my source's lib folder, compiled again, also couldn't find expat library.

Then, I downloaded expat source. First, did ./configure, then did make. When making, message was:
ld: Unknown input file type: "./.libs/libexpat.so"
Fatal error.
*** Error exit code 1
Under .libs folder, libexpat.a and libexpat.so had been created.
I copied this licexpat.a to my lib folder, also couldn't use.

The same source, I compiled on AIX5.3, Linux, Windows.... no problem.

Anybody could explain? Kindly thanks!

Kind Regards,
Arthur Zhu

Hi Mauad,

I'm so glad to hear from you.

I also used sqlite. But I'm not familiar with it.
My projects are usually under Windows Platform. But the project needs to
run under Linux, AS400, Solaris, hpux, AIX, Windows. I'm not famaliar with
Unix and Linux.
My msn: dongpaidoudou at msn.com
 Email: arthurzhuwei at gmail.com or gongxifacai at yahoo.cn

Could you tell me your msn or mail address? If I have some problem, I
think I could get help from you.
Thanks!

Kind Regards,
Arthur Zhu

Hi Arthur!

Thanks! 


I'm sorry, but I had not figured out that your CC was cc. Mine was gcc ;)
I had a similar problem with sqlite some time ago. Subtle gotchas.


Best regards.

Hi, mauad,

I'm so glad to get response from you.
I found the problem.
First, the depot is ok.
But when I compiled source(Version2.0.1), error occured.
My step was:
./configure
make // when making, can't find libexpat.a.
I checked the "Makefile". Changed the line 106: from "CC = cc" to "CC = cc
+DSitanium2 + DD64 +w1". Then make again, also had some problem. But the
libexpat.a could be used.
I thought that's the problem. If I didn't change "Makefile", compiled
libexpat.a is 32bit, after changed, compiled libexpat.a is 64bit.

Kind Regards,
Arthur Zhu in Shanghai

This looks weird.

After downloading sources, I'd built expat on an Itanium server using the
following setup:

* gcc -v:
Using built-in specs.
Target: ia64-hp-hpux11.23
Configured with: ../gcc/configure
Thread model: posix
gcc version 4.1.1

GNU Make 3.81

After building the vanilla version (running ./configure)
with:
* make 
* make install

the files under examples/ were built, and the uutput was the expected upon
some XML files.

Note that the propper .so was built: 
* ldd /usr/local/lib/libexpat.so

/usr/local/lib/libexpat.so:     ELF-32 shared object file - IA64


It seems that your HPUX depot is influencing the linker.

Try out this steps:

1. Check which depot was downloaded (look for the IA64 one! there is a PA
and a IA64 version for 11.23) 
   with file $PATH_TO_EXPAT_LIB/libexpat.so

2(a). If the depot is wrong, you don't have a bug
2(b). If the depot is ok, uninstall it before rebuilding
3. Rebuild expat from scratch with ./configure, make make install
5. Change to examples/ and execute gcc -o elements elements.c -lexpat
6. Try it out with elements < file.xml
