I have just compiled libxml2 the same way on the two computers : ./configure --prefix=... make make install On the first computer, I got the compile problem. On the second computer, I got no problem when compile. So, I think the problem is about gcc on the first computer. What should I do to compile fine my program with gcc on both computers? ----- Mail original ----- De: "Ryan Mansfield" <rmansfield@xxxxxxx> À: gcc-help@xxxxxxxxxxx Envoyé: Mercredi 15 Février 2012 15:49:04 Objet: Re: The order of arguments differs On 12-02-15 09:41 AM, spam.spam.spam.spam@xxxxxxx wrote: > Hello, > > I am compiling a program on 2 computers. > > Table of contents > 1.

Check with -Wl,-t. Link order matters when statically linking; the reference always has to come before the symbol definition (unless you use -start-group/--end-group to have ld make a second pass) > Do you think it's a gcc problem? No. Regards, Ryan Mansfield
