编译“stress-ng”包的静态链接可执行文件

Question

I'm trying to compile the "stress-ng" package to produce a statically linked executable to use it inside GEM5 full system simulator.

A tarball of this package can be downloaded here . The version I'm trying to compile is 0.07.08.

To compile a dynamically linked executable of this package, just "make". This works for me.

However, since I need to run the "stress-ng" exe from within a GEM5 full system simulation, I need to make sure that the exe is self-contained. This is usually done using the "-static" CFLAG option, however, for "stress-ng", I get an error when I try this option.

Here is what to do in order to reproduce this error. Edit "Makefile" and add "-static" option at the end of line # 25. Line 25 should look like the following:

CFLAGS += -Wall -Wextra -DVERSION='"$(VERSION)"' -O2 -std=gnu99 -static

Save then make, you will see the error below:

/usr/lib/gcc/x86_64-linux-gnu/4.6/../../../x86_64-linux-gnu/libpthread.a(lowlevellock.o): In function `__lll_lock_wait_private':

collect2: ld returned 1 exit status
make: *** [stress-ng] Error 1

Finally, OS is Ubuntu 14.04 and cc version is 4.6.4.

Am I missing some other CFLAG option(s) here?

I've pushed a new fix to the stress-ng repo that now allows static linking. The issue was that -lc was before -lpthread, which caused the problem.

Pull the latest changes and then build with:

STATIC=1 make
