GCC First Pass Error: C Compiler cannot create executables

firephyz · 01-07-2017, 06:13 PM

I've been trying to build the first pass of GCC for LFS 7.10 (GCC 6.2.0). I was able to successfully build binutils but no matter what I try with gcc, it always quits when building libatomic and complains that the C compiler cannot create executables.

By examining the config.log, I noticed that it was referring to not my system's c compiler but the test compiler it's building called xgcc. Thus, I tried to compile my own dummy hello world file with this compiler. This errored out with the following error:

Code:

xgcc: error trying to exec 'cc1': execvp: No such file or directory

I know this normally happens when the compiler can't find cc1 because of a missing link or something but in this case, cc1 is present in the same directory as xgcc so I don't quite understand what to do from here.

Here is the make command error:

Code:

I configured gcc as LFS 7.10 prescribes. Thanks for any help!

business_kid · 01-08-2017, 12:02 PM

You don't necessarily need cc1 in the same directory, you need it in the $PATH. Does the 'which' command find your cc1? If not try this

Code:

ln -s /path/to/your/cc1 /usr/bin/cc1

and try the recompile.

firephyz · 01-08-2017, 01:11 PM

So it turns out my host system doesn't have cc1 anywhere in PATH. THere is, however, a copy of it in the gcc build directory that I presume gcc built. So now, I tried recompiling my test program using xgcc but with the

Code:

-B/mnt/lfs/sources/gcc-6.2.0/build/gcc

so that gcc which search that directoy. This seems to have gotten rid of the cc1 error but now it's complaining that it can't find stdio.h

business_kid · 01-09-2017, 04:53 AM

Building LFS, 2 errors was always a signal to me that you have set up the environment wrong.

You shouldn't be building libatomic at all. It's one of a number of libraries that don't work in a cross-compiler. Look again at the configure command for first-pass gcc and you will see that libatomic should be disabled together with a string of other libraries.

--disable-decimal-float, --disable-threads, --disable-libatomic, --disable-libgomp, --disable-libmpx, --disable-libquadmath, --disable-libssp, --disable-libvtv, --disable-libstdcxx

These switches disable support for the decimal floating point extension, threading, libatomic, libgomp, libmpx, libquadmath, libssp, libvtv, and the C++ standard library respectively. These features will fail to compile when building a cross-compiler and are not necessary for the task of cross-compiling the temporary libc.
