I have run into a problem when trying to build a shared library. Here is the output of the build process - which seems to run just fine:<BR /><BR />ld -b -o libz.sl.1.1.3 adler32.o compress.o crc32.o gzio.o uncompr.o deflate.o trees.o zutil.o inflate.o infblock.o inftrees.o infcodes.o infutil.o inffast.o +h zlib.dll<BR /><BR />ld: (Warning) At least one PA 2.0 object file (adler32.o) was detected. The linked output may not run on a PA 1.x system.<BR /><BR /> rm -f libz.sl libz.sl.1 <BR /> ln -s libz.sl.1.1.3 libz.sl <BR /> ln -s libz.sl.1.1.3 libz.sl.1 <BR /> cp libz.sl /home/intergy/Code/Shared/Core/bin/ZipUtility/zlib.dll <BR /> chmod 777 /home/intergy/Code/Shared/Core/bin/ZipUtility/zlib.dll <BR /><BR />The last two lines copy the library to our directory and sets it to be world executable/writeable/readable ... <BR /><BR />When I try to use it from within our system, I get this message: <BR /><BR />/usr/lib/pa20_64/dld.sl: '/home/intergy/Code/Shared/Core/bin/ZipUtility/zlib.dll' is not a valid load module: Bad magic number<BR /><BR />When looking at the file using the UNIX file command, I get: <BR /><BR />file /home/intergy/Code/Shared/Core/bin/ZipUtility/zlib.dll <BR />/home/intergy/Code/Shared/Core/bin/ZipUtility/zlib.dll: PA-RISC2.0 shared library -not stripped <BR /><BR />Which looks all right to me. Anyone knows how I can get around this? Thanks in advance.<BR /><BR /> Tue, 25 May 2004 13:50:58 GMT https://community.hpe.com/t5/operating-system-hp-ux/compiling-shared-libraries-question/m-p/3286432#M715578 Jimmy Tom_2 2004-05-25T13:50:58Z https://community.hpe.com/t5/operating-system-hp-ux/compiling-shared-libraries-question/m-p/3286433#M715579 Almost sounds like a mis-match between 32 and 64 bit libraries....<BR /><BR />Rgds...Geoff Tue, 25 May 2004 14:11:20 GMT https://community.hpe.com/t5/operating-system-hp-ux/compiling-shared-libraries-question/m-p/3286433#M715579 Geoff Wild 2004-05-25T14:11:20Z https://community.hpe.com/t5/operating-system-hp-ux/compiling-shared-libraries-question/m-p/3286434#M715580 It is definitely complaining about trying to load a 32-bit shared library from a 64-bit program.<BR />You need to compile the files for the shared library with a "+DD64" or "+DA2.0W" option to create 64-bit code.
