c - Linking with ld/gcc doesn't produce same result (error/sucess) -

-

i have problem, after compilation wan't link using ld when error lets see do:

make i386 gcc -g -c -i. -i/usr/include -o p_test.o.i386 pkcs11test.c ld -o p_test.i386 p_test.o.i386 -g -ldl      ld: p_test.o.i386: référence au symbole non défini «fflush@@glibc_2.0» //lib/i386-linux-gnu/libc.so.6: error adding symbols: dso missing command line make: *** [i386_p_test] erreur 1

so ld got error when try gcc 

make i386 gcc -g -c -i. -i/usr/include -o p_test.o.i386 pkcs11test.c gcc -o p_test.i386 p_test.o.i386 -g -ldl

i got no error , executable

do know how can make ld work linking program ?

thanks !

when start gcc gcc -o p_test.i386 p_test.o.i386 -g -ldl, adds lot internal libraries ld command. can see arguments adding -v option gcc. 1 of "internal library" glibc (-lc).

for example, here gcc verbose mode output explanation can see collect2 program used link executable. there -lgcc -lgcc_eh -lc -lgcc -lgcc_eh libraries added run , several crt runtime objects linked too:

/usr/lib/gcc-lib/i686/3.3.1/collect2  --eh-frame-hdr -m elf_i386 -dynamic-linker  /lib/ld-linux.so.2 /usr/lib/crt1.o /usr/lib/crti.o  /usr/lib/gcc-lib/i686/3.3.1/crtbegin.o  -l/usr/lib/gcc-lib/i686/3.3.1  -l/usr/lib/gcc-lib/i686/3.3.1/../../..   /tmp/ccqynbtm.o  # << input file.  -lgcc -lgcc_eh -lc -lgcc -lgcc_eh  /usr/lib/gcc-lib/i686/3.3.1/crtend.o  /usr/lib/crtn.o

ps: think better not change file extensions (suffixes). p_test.o.i386 can renamed p_test.i386.o

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
