What is that? I'm seeing that compiler warning in my fpGUI projects too? Since I upgraded to 3.0.4 using Linux 64-bit. It was not there in FPC 2.6.4.

Below is a sample output done by Joost, which shows the same warning in a simple One Form LCL based project.

That one has been around for some time now on *nix. The linker wants that file.
There's a commandline argument to gcc that will tell you where it is. Then add that path in the appropriate place in fpc.cfg (At least I did that on Mint 18.2 and Suse Tumbleweed)

~ $ gcc --print-file-name crtbeginS.o
/usr/lib/gcc/x86_64-linux-gnu/5/crtbeginS.o

from /etc/fpc.cfg:

# path to the gcclib
#ifdef cpui386
#-Fl/usr/lib/gcc/x86_64-linux-gnu/5
#endif
#ifdef cpux86_64
-Fl/usr/lib/gcc/x86_64-linux-gnu/5
#endif

Thanks for the reply and your second email. I normally code under FreeBSD (for the last 7 years), so maybe I already fixed it there, but forgot about it. Also, FreeBSD's userland and base OS directory layout is very different (more organised) to Linux. I only recently set up a new Ubuntu Linux development system with everything a fresh install, and that is where I see this compiler warning.

I just made the changes you suggested and the warnings are now gone. Awesome. Thanks again.

Graeme

I put it on my user page on the wiki:

I added it to the explanation of the compiler error.

I added it to the FAQ.
