RE: Install Apache 2.4.20 on Solaris 10 --- Error "ld: fatal: file ab.o: wrong ELF class: ELFCLASS32"

"Huang, Jinhui (OST)" <Jinhui.Huang.CTR@xxxxxxx> · Fri, 29 Apr 2016 14:20:15 +0000

Hi, Rainer:

The following is the new error I received when I try to install Apache 2.4.20 again, using new PCRE 8.38. I have added a shortened screen capture (zptpt-20160428e-short.txt) as attachment. The original file is about 4.4 MB. In this short version, 45650 lines of make output have been deleted. Please let me know if you need the completed output.

Thank you for the advice of using pcre 8.38. I installed it last night successfully to replace the old. 

When I first try to install it using
#  export CC="gcc -m64"
#  ./configure --prefix=/usr/local/apache2/pcre/ # make I received the following error,

The following command caused the error:

Inspired by the example I searched online, I added one more option (--disable-cpp) to the configure. Then the pcre was installed successfully:

# ./configure --prefix=/usr/local/apache2/pcre --disable-cpp ...
# make clean
...
# make
...
...

ld: warning: file /usr/local/apache2/install/pcre-8.38/.libs/libpcre.so: linked to ./.libs/libpcre.so: attempted multiple inclusion of file # # make install ...

I hope the two warnings during make are not important.  Please let me know if you need to see the whole screen capture (text file).

Last night, after the install of the PCRE 8.38, I tried the Apache installation again. This time I got a different error message. I will post it very soon.

This error is likely a consequence of the error during configure:

checking for pcre-config... false

configure: Using external PCRE library from /usr/local/apache2/pcre2/bin/pcre2-config

   setting PCRE_INCLUDES to "-I/usr/local/apache2/pcre2/include"

Usage: pcre2-config [--prefix] [--exec-prefix] [--version] [--libs8] [--libs-posix]  [--cflags] [--cflags-posix]

   setting PCRE_LIBS to ""

Usage: pcre2-config [--prefix] [--exec-prefix] [--version] [--libs8] [--libs-posix]  [--cflags] [--cflags-posix]

This indicates that your try to build httpd against pcre version 10. We only support pcre until version 8, latest is 8.38. PCRE version 10, aka pcre2, is not API compatible with pcre until 8. Since the path /usr/local/apache2/pcre2/ looks like you compiled pcre2 yourself, grab pcre 8.38, compile it again and run configure against that one.

This will IMHO *not* fix you other issue about ab.o being 32 bit. Could it be, that ab.o was in your build directory from another attempt at building where you started without the -m64 flag, so that there was already an old 32 bit ab.o file and "make clean" has already fixed that?
