Linking problem in firefox 1.5 ?

[sabarinathan]

Hi All, I had built a xpcom component for Firefox 1.5 in linux. Then i placed the component under firefox/components/ directory. Now i tried to execute `ld components/libqecomp_FIREFOX_1.so` to find any failed dependencies. It throwed the error (given below Error from ld command). Hence as given in the warning i executed `ld -rpath . components/libqecomp_FIREFOX_1.so` from firefox folder. Then the ld doesn't throw any error. So i assume there may be a problem in linking while creating the component. The following is the command that is executed to link the component against needed libraries, c++ -I/usr/X11R6/include -fno-rtti -fno-exceptions -Wall -Wconversion -Wpointer-arith -Wcast-align -Woverloaded-virtual -Wsynth -Wno-ctor-dtor-privacy -Wno-non-virtual-dtor -Wno-long-long -pedantic -fshort-wchar -pthread -pipe -DNDEBUG -DTRIMMED -fPIC -O  -shared -Wl,-h -Wl,libqecomp_.so -o libqecomp_.so src/Debug.o src/regex.o src/nsRecorderImpl.o src/nsQEngineImpl.o src/nsQEngineModule.o src/ClientSocket.o src/nsPlayBack.o src/nsPlayBackUtils.o src/nsValidator.o   -Wl,--version-script -Wl,/home/sabarinathan/srini/src/mozilla/build/unix/gnu-ld-scripts/components-version-script -Wl,-Bsymbolic /home/sabarinathan/srini/src/mozilla/dist/lib/libxpcomglue_s.a -L/home/sabarinathan/srini/src/mozilla/dist/bin -lxpcom -lxpcom_core -L/home/sabarinathan/srini/src/mozilla/dist/bin -L/home/sabarinathan/srini/src/mozilla/dist/lib/ -lplds4 -lplc4 -lnspr4 -lpthread -ldl -L/home/sabarinathan/srini/src/mozilla/dist/lib -lmozjs -lnss3 -lxpcom_compat -lpthread  -ldl -lm The component is linked against the libraries from the compiled firefox 1.5 source (/home/sabarinathan/srini/src/mozilla/). Please let me know whether it is a problem with linking or any environment variable.
