[SOLVED] LFS 9.0

Sasquiche · 03-18-2020, 07:14 PM

This is a head scratcher.

Code:

In file included from ../../../libgcc/gthr.h:148,
                 from ../../../libgcc/unwind-dw2.c:37:
./gthr-default.h:35:10: fatal error: pthread.h: No such file or directory
   35 | #include <pthread.h>
      |          ^~~~~~~~~~~
compilation terminated.
make[2]: *** [../../../libgcc/static-object.mk:17: unwind-dw2.o] Error 1

I've attempted to compile GCC 3 times now. The first had no issues, but had to redo ch5 after a failure with the API headers. I'm worried attempting to restart the first time and clearing out my tools dir may have caused this issue (strangely I wasn't auth to delete the tools dir) OR an issue with the binutils compile.

I'm not familiar with where this include is being sourced from, but if anyone could point me to where it is that would be helpful. Also when troubleshooting make errors what are some troubleshooting tips you could recommend?

phread.h is installed by glibc you probably forgot to do make install.

Quote:

pthread.h: No such file

Code:

# apt install --reinstall libc6-dev
      // provides /usr/include/pthread.h

Thank you for the replies.
That's where I'm scratching my head. pthread.h is in /usr/include on my host machine

So I created a dummy.c file and compiled it with gcc, with no error to output:

Code:

#include <pthread.h>

int main(){}

However if I follow lfs, doesn't the "--with-local-prefix=/tools" option during the .configure precompile set up "make" to look in /tools for locally installed include files, instead of /usr/include?

Or I'm off base here?

Sorry misread your op, you wont have installed glibc yet, are you sure you did all the gcc prep bits? sed etc, also check your configure for gcc as the 1st pass should have this option "--disable-threads" in the configure.

As you are so close to the start of building the tools I would suggest you completly clean your LFS system and start from scratch, problems at this early stage can cause weird errors later on.

Sasquiche · 03-20-2020, 09:30 AM

Keith you were spot on about the "--disable-threads" option.

... I misspelled "thread" on both clean attempts.

Just compiled again, with no issues.

The lesson here is DOUBLE CHECK THE SPELLING OF YOUR COMMANDS; especially before configuration, double check the spelling of your options.

Thanks for your responses.

No worries, glad you got it working.
