Re: fatal error: pthread.h: No such file or directory

Hi all,

I bring this post back on top.
I'm currently trying to build a crosstool for x86 plateform with the
sample "x86_64-unknown-linux-uclibc"

Each time I compile it (whenever changes of the kconfig (bitness
apart)) I have the error "fatal error: pthread.h: No such file or
directory" on compilation of
"gcc-5.2.0/libgcc/generic-morestack-thread.c" (error:
http://pastebin.com/ESkQ68eD)


I've seen this post and the Waldemar suggest to use this patch (made
for buildroot): http://patchwork.ozlabs.org/patch/592962/

Did anyone test it or made an updated one for crosstool-ng?
Is it safe to use it without any changes?

I'm not used to build crosstools and apply patches, I'm still leaning.

Thank for your assistance.

Regards,
Marc-Antoine Martin

This patch is in crosstool-ng default patchset on master, so it should 
be applied automatically.

You're using a 1.22, apparently - I just checked, it did not have that 
patch.

You can either try a snapshot of the master branch, or put the patch for 
your version into <somedir>/gcc/5.2.0; then select "bundled,local" as 
the patch order and specify <somedir> as the local patch directory.

Don't forget to do `ct-ng clean` before re-running the build.

Regards,
Alexey.

Hi,

I recently seen this when Threads are disabled.

I submitted a patch to buildroot, which might be used here,
too:http://patchwork.ozlabs.org/patch/592962/

Best regards

Hi Yann,

Pulling latest git, I make, then do this to use built in recipe

./ct-ng x86_64-unknown-linux-uclibc

Everything builds fine.


If I do the same but only change (via ct-ng menuconfig) the target to
be 32 bit rather than 64 bit I get this on pass-2;

I have tried altering various versions of build tools and it is always
the same error.
(I tried attaching build.log but it just bounced so resending without)
