I'm having issues building and linking a library that I created to another executable. Below are the steps that I followed. NOTE: I'm building this project on my computer (Ubuntu Karmic Koala) and then putting it on to an embedded arm device running busyBox linux. Here's the steps that I've gone through that lead me to a dreaded "cannot find MYLIB.so" when I try and run the application on the embedded device 1: arm-linux-gcc -Wall -fPIC -c MYLIB.c -O3 --sysroot home06 2: arm-linux-gcc -Wall -shared -Wl,-soname,libMYLIB.so.1 -o libMYLIB.so.1.0 MYLIB.o -O3 --sysroot home06 3: ln -sf libMYLIB.so.1.0 libMYLIB.so //symbolic link for -lMYLIB 4: ln -sf libMYLIB.so.1.0 libMYLIB.so.1 //allows for runtime binding to work 5: arm-linux-gcc -lTXRX -lm -lMYLIB COMM.c -O3 --sysroot home06 -o RUNONBOX 6: ldd RUNONBOX >> not a dynamic executable //this doesn't seem good...no reference to >> MYLIB... NOTE: I've built this program with -lTXRX and -lm many times >> before with ZERO issues 7: mput *.so* //put all symbolic links on device NOTE: folder is /tmp/cf 8: put RUNONBOX //put executable on device NOTE: folder is /tmp/cf 9: export LD_LIBRARY_PATH=/tmp/cf/:$LD_LIBRARY_PATH 9: ./RUNONBOX >> can't load library 'libMYLIB.so' The questions that I have are A: Why won't my library be loaded even though I've set the LD_LIBRARY_PATH to look in the directory with libMYLIB.so? B: How do I have 2 other libraries that are linked to this program that do not show dependencies when I run 'ldd'? NOTE: these libraries are on the embedded device, but are in a folder where I can't place my links and libMYLIB.so C: Is there anything else I can try?:working: -- View this message in context: http://old.nabble.com/Shared-Libary-Issue---cannot-find-library-tp33352272p33352272.html Sent from the gcc - Help mailing list archive at Nabble.com.
