Hi,

I tried to build LTP modules from following git:

"Fix make filed,, reported by Shi Weihua <[email protected]>" (ltp-dev-c962f51674b971496e14ac4be0cc75da98b75fca.tar.gz)

But I failed to build "check_for_unshare.c" in RHEL5.4 system (2.6.18-164.el5).

I think that "-ldl" is needed in options.

Hi Mitani,

I am able to compile with changing LDLIBS as done by commit : 1a5506c97dcfda0bd16f83ca855bb633c47eea4c

on RHEL5.4 .

Can you try configuring once again ?

Let me know when you face again some prob.

Hi, Rishikesh

I tried to build again with recent git today and I could build.

I neglected attention and did not notice new git.

I'm sorry and thank you for your information!

I realize that this has already been resolved, but just to make
sure we're all clear LDLIBS should contain -l arguments, LDFLAGS should contain all non- -l arguments which get passed to ld(1), CPPFLAGS should contain all items which need to get passed to cpp(1) and cc(1), and CFLAGS should contain everything that needs to go strictly to cc(1).
So... -l arguments should _NEVER_ be put in CFLAGS.
Thanks,
