Compiling on openbsd with gcc4.8, executables fail to run

[Riccardo Mottola]

Hi,

I wanted to compile gnustep on OpenBSD by using gcc 4.8.1 from ports, 
instead of the standard, old gcc 4.2.1 compiler.

the additional compiler is called "egcc", I thus configured base with:
./configure CC=egcc CXX=eg++

make was configured with:
$ ./configure --with-layout=gnustep --prefix=/ CC=egcc CXX=eg++

Everything compiles quickly and easy!

however, when I try to run a binary, I get

$ plparse
plparse:/Local/Library/Libraries/libgnustep-base.so.1.24: undefined 
symbol '__objc_msg_forward2'
Segmentation fault (core dumped)


why this? I don't know. I tried to ldd:

my suspect is that         05b92000 25b9b000 rlib 0    1   0 
/usr/lib/libobjc.so.5.0

is the wrong libobjc, it is the one of the default compiler. It should be:

$ ls -l /usr/local/lib/libobjc.*
-rw-r--r--  1 root  bin  544350 Jul 22 16:53 /usr/local/lib/libobjc.a
-rwxr-xr-x  1 root  bin     927 Jul 22 16:53 /usr/local/lib/libobjc.la
-rwxr-xr-x  1 root  bin  500970 Jul 22 16:53 /usr/local/lib/libobjc.so.5.0


even if it is 5.0

How may I fix this?
