I was trying to build an fpc for clang 16 (same commands worked on a diff machine for clang 11)

I changed the version in the make line:
  make all  OPT=" " OPTNEW=" -Clv16.0 " FPCMAKEOPT=" -Clv16.0 " LLVM=1

I also tried version 16.0.6

fpc 49cb7b256476409924c581145a760b863b9e755d
(I had tried earlier with an older fpc on that machine. I don't know if the error was the same)

clang --version
clang version 16.0.6 (Fedora 16.0.6-3.fc38)
Target: x86_64-redhat-linux-gnu
Thread model: posix
InstalledDir: /usr/bin

But I am getting

The -Clv parameter is missing here for some reason, so the compiler is generating code for LLVM 7.0 rather than 16.0.

Jonas

It seems to happen during "make install". Strange, why does it compile during installation?

My script issues the following commands:
(I am using the same on another machine with clang 11)

make clean
make all  OPT=" " OPTNEW=" -Clv16.0 " FPCMAKEOPT=" -Clv16.0 " LLVM=1 make install INSTALL_PREFIX=/home/m/fpc/$INSTPATH/def  LLVM=1

The captured output does not have the commands itself, only the output.... The "100%" should still be from the "make all" (there is no install in the text before that)

I assume "installbase" is the start of the output of above make install.

And then it starts the compiler.... Why?

Before that there are 10 other occurrences of

I also looked for msg2inc. And msg2inc was compiled before

msg2inc.pp is only twice in the log. As below, and as in the error above

Without the pp extension it is present in a few "rm". All above the below snippet

Starting compiler is 3.2.2

I should mention that the compiler is not installed to /usr/.... , nor anywhere in a global available place. (As I have several versions on that machine, I made sure non of them has anything in a place where it could be found by others.  (that includes no /etc/fpc.cfg, nor fpc.cfg in my home dir. / each fpc has an fpc.cfg inside its install dir)

But before the make is called the PATH is set to include the 3.2.2 fpc.

I use identical setup on several Linux boxes, including the one that successfully build with clang 11

Maybe check the timestamps of compiler/msg*.inc,
compiler/utils/msg2inc.pp and compiler/msg/errore.msg. Perhaps some of those have timestamps far in the future?

Jonas

The seem ok to me. Either checkout date, or build date.

Anyway, I changed the make
     make install INSTALL_PREFIX=/home/m/fpc/$INSTPATH/gw3  OPT=" -Clv16.0 " LLVM=1

Then next it fails, with the same error on
    make clean

Yes, it tries to compile a file while doing "make clean"

Interestingly, "make clean" refuses to start, unless it has a compiler in path (ok, even if it should not need it, as it should not compile anything...), but then it uses  source/compiler/ppc1

Even stranger, if I do  delete the ppc1 before "make clean" rm /home/m/fpc/$INSTSRC/source/compiler/ppc*

Then "make clean" will build a new ppc1. Why?

9. prosince 2023 18:24:10 SEČ, Martin Frb via fpc-devel napsal:

I believe that it might be because the compiler is used in FPC makefiles to determine the default target (used if no target is specified on the make command line specifically) and this target determines the location of files to be cleaned.

Tomas

As Tomas mentioned, this is required to know which target to clean.

You can try specifying FPC=$PWD/compiler/ppcx64 when doing the "make install" to ensure it has the same default target as the one that was just built.

If all else fails, you can try remake to see why it is recompiling things: https://github.com/rocky/remake/
