while on machine using 4.3 toolchain, it looks ok.

Follow-ups

are you building with an older toolchain (one that has stubs) but then running

on a newer one ? the strace code now checks for fork() at configure time and

then will avoid using it if fork() is not found.

please post the config.log from the strace build dir

--- Mingquan Pan 2009-11-02 21:02:43

On the test machine, the 4.1 09r1-9 toolchain used to build strace also is used

to build the kernel that the strace is running on. They are the same toolchain.

I copy over the config.log from the build dir, see attached.

--- Mike Frysinger 2009-11-02 21:11:17

you cant build things with the 2009R1 toolchain and have things work under

trunk. the trunk toolchain doesnt provide fork() and such stubs like the 2009R1

toolchain did.

After updating to trunk head toolchain, strace can run ok now. So close.
