Possibly unwisely, I updated by Mac to Mojave. I found that things (including 32 bit apps) worked, but:

I had to add

-Fl/Applications/Xcode.app/Con
tents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/lib

to my fpc.cfg to avoid "/usr/lib/crt1.o not found" errors. It seems as though the startup files are no longer in /usr/lib

The gdb from MacPorts also didn't seem to work. I had some success using lldb - I notice an alpha package for this can be installed in lazarus, and this seemed to work, at least on the basic test I did.

I didn't see that thread. I can confirm that
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/lib/ exists on my system

Colin

I've created an FPC 3.0.4a release for macOS yesterday that adds the appropriate directives to /etc/fpc.cfg (no changes to the compiler).

I just realized on a freshly set up computer that there is one more issue, I tried to build the trunk x86_64 compiler and compile fails:

/bin/mkdir -p x86_64/units/x86_64-darwin
/Applications/Xcode.app/Contents/Developer/usr/bin/make ./msg2inc /usr/local/bin/ppcx64 -Ur -Xs -O2 -n -Fux86_64 -Fusystems -Fu/Users/ring/devel/fpc/rtl/units/x86_64-darwin -Fix86_64 -FE. -FUx86_64/units/x86_64-darwin -dRELEASE    -dx86_64 -dGDB -dBROWSERLOG -Fux86 -Sew -FE. utils/msg2inc.pp
ld: file not found: /usr/lib/crt1.10.5.o
An error occurred while linking
msg2inc.pp(822,51) Error: Error while linking
msg2inc.pp(822,51) Fatal: There were 1 errors compiling module, stopping Fatal: Compilation aborted

problem is that ppcx64 is called with option -n so fpc.cfg gets ignored.

I guess the only way to fix this is to change the makefile itself.

Also, one thing I do not understand in /etc/fpc.cfg installed by the 3.0.4a installer, why if -Fl ifdef'ed for i386 only?

#ifdef cpui386
-Fl/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/lib #endif

Here's the patch for the makefile that worked for me:

I meant to mention in my original message that I needed to add

OPT=-Fl/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/lib

to the end of the make distclean install I use to compile the trunk compiler.

My fpc.cfg also has #ifdef darwin, rather then #ifdef i386.

Colin

As Colin mentioned, you can pass the necessary options to make via OPT="-option1 -option2"

It's because the necessary files for x86-64 can be found in /usr/lib, where the compiler looks by default.

Jonas

Until now you could compile trunk without such specific opts, so making OPT= something mandatory for future builds of trunk to work at all does not sound like a good plan to me.

and no, at least in my installation there are no crt1* files in /usr/lib, if there were any we would not have this discussion here ;-)

I am not trying to solve something for myself, my own builds are working for quite a long time on Mojave, just wanted to make sure that compiling trunk keeps as straightforward as ever....

I committed a fix that could be merged to 3.0.4 without having to change the compiler, in order to minimise the chances of introducing any bugs in an existing release. Maybe I'll hardcode new paths in the compiler as well, but hardcoding new paths in the compiler every couple of new macOS releases is not a good plan either.

There indeed are none, that is why for x86-64 there is a -XR/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk option in fpc.cfg. That does not work for i386, because the libraries in that SDK don't contain i386 versions. Only the versions installed as part of the operating systems do (but the crt1.o file for i386 is only there, hence the -Fl statement for that architecture).
