this does not work for several reasons: 1. I certainly need -std=c99 for the inline initialisation of the counter in the for() statement. 2. *section (first used in »gelf_getshdr(section, §ion_header)«) isn't defined/filled anywhere: # $ gcc -g -lelf -std=c99 -o elfrel elfrel.c # elfrel.c: In function ‘main’: # elfrel.c:26:24: error: ‘section’ undeclared (first use in this function) # if (gelf_getshdr(section, §ion_header) != §ion_header) # ^ # elfrel.c:26:24: note: each undeclared identifier is reported only once for each function it appears in While defining »Elf_Scn *section;« gives me a compiling elfrel.c, it unsurprisingly doesn't do anything afterwards, since section is empty. Long story short: did you paste the entire/correct code? Maybe just attach the file and send an MD5 or something along. Cheers, Kai
