[Mapserver-users] Perl Mapscript (with Mapserver-3.6.3) on Redhat 8 compiles, but returns __gxx_personality_v0 when tested

[Dana Quinn]

Jonathan, etal-
	I had the same problem using perl mapscript.  I think you
basically need to compile the lib with c++ instead of the regular
gcc.  The way I did it was really low tech, because I couldn't
figure out what needed to be in Makefile.PL or Makefile.
here is exactly what I did:  (my build environment is sorta
strange, don't worry about all the extra -I's)

[prompt]$ perl Makefile.PL
-I/u1/src/ms/mapserver-3.6.3 -I/u1/src/ms/proj/include -I/u1/src/ms/gd
-L/u1/src/ms/mapserver-3.6.3 -lmap -L/u1/src/ms/gd -lgd 
-L/u1/src/ms/freetype2/lib -lfreetype -lz -L/u1/src/ms/freetype2/lib 
-lfreetype -lz -L/u1/src/ms/proj/lib -lproj -lm
Writing Makefile for mapscript
[prompt]$ make
cp mapscript.pm blib/lib/mapscript.pm
cc -c  -I/u1/src/ms/mapserver-3.6.3 -I/u1/src/ms/proj/include 
-I/u1/src/ms/gd -fno-strict-aliasing -D_LARGEFILE_SOURCE 
-D_FILE_OFFSET_BITS=64 -I/usr/include/gdbm -O3   -DVERSION=\"\" 
-DXS_VERSION=\"\" -fpic "-I/usr/local/lib/perl5/5.8.0/i686-linux/CORE" 
-DIGNORE_MISSING_DATA -DUSE_EPPL -DUSE_PROJ -DUSE_PROJ_API_H 
-DUSE_GD_GIF -DUSE_GD_WBMP -DUSE_GD_FT -DGD_HAS_GDIMAGEGIFPTR 
mapscript_wrap.c
Running Mkbootstrap for mapscript ()
chmod 644 mapscript.bs
rm -f blib/arch/auto/mapscript/mapscript.so
LD_RUN_PATH="/u1/src/ms/mapserver-3.6.3:/u1/src/ms/gd:/u1/src/ms/freetype2/lib:/usr/lib:/u1/src/ms/proj/lib:/lib" 
cc  -shared -L/usr/local/lib mapscript_wrap.o  -o 
blib/arch/auto/mapscript/mapscript.so   -L/u1/src/ms/mapserver-3.6.3 
-lmap -L/u1/src/ms/gd -lgd -L/u1/src/ms/freetype2/lib -lfreetype -lz 
-L/u1/src/ms/freetype2/lib -lfreetype -lz -L/u1/src/ms/proj/lib -lproj -lm
chmod 755 blib/arch/auto/mapscript/mapscript.so
cp mapscript.bs blib/arch/auto/mapscript/mapscript.bs
chmod 644 blib/arch/auto/mapscript/mapscript.bs

then - I took the last line that ran cc - copy and paste it back onto 
the command line, and then edit the 'cc' to be 'c++'

and then run it:
[prompt]$ 
LD_RUN_PATH="/u1/src/ms/mapserver-3.6.3:/u1/src/ms/gd:/u1/src/ms/freetype2/lib:/usr/lib:/u1/src/ms/proj/lib:/lib" 
c++  -shared -L/usr/local/lib mapscript_wrap.o  -o 
blib/arch/auto/mapscript/mapscript.so   -L/u1/src/ms/mapserver-3.6.3 
-lmap -L/u1/src/ms/gd -lgd -L/u1/src/ms/freetype2/lib -lfreetype -lz 
-L/u1/src/ms/freetype2/lib -lfreetype -lz -L/u1/src/ms/proj/lib -lproj -lm

and as far as I can tell, the lib works fine. sorry for the bad 
linewrap, hopefully you get the idea.  Hopefully someone smarter than me 
can figure out how to include this in configuration.  :)
