Turns out ./dist/lib/ remained from the previous install, which I didn't delete
before testing with --libdir=$(pwd)/dist/mylibs.

Indeed, it only creates ./dist/mylibs, and indeed it fails to find the dylib
when running ./dist/bin/tcc, (make test still works).

Thanks. I can confirm current mob (6c94df6) does work also with custom prefix,
as well as building in a custom dir (mkdir build && cd build && ../configure ...).

However, looking at that commit, I thought it would break with a custom --libdir,
like ./configure --libdir=$(pwd)/dist/mylibs but I tried it and it still worked.

Turns out it creates both ./dist/lib and ./dist/mylibs, and libtcc.dylib is at both
of them as well as tcc/ and its content (duplicated at both dirs), though libtcc.a
is only at ./dist/lib/ .

Is that expected? I never tried using --libdir before, but commit 6c94df6 makes it look
a bit hardcoded, so I tried it now. Wouldn't it be better to specify the absolute
install [libdir] ?

I’ve found another (and better) way to achieve this:

-Wl,-rpath,"@executable_path/$(TOP)" -Wl,-rpath,"@executable_path/$(TOP)/../lib"

It is commited, can you please test this one.

Thanks avih, another step is missing (it works well with default install location)

Can you please test this:

$ install_name_tool -add_rpath "@executable_path/../lib/" tcc

$ make install

$ ./dist/bin/tcc -vv

tcc version 0.9.27 (x86_64 Darwin)

install: /Users/jullien/tinycc/dist/lib/tcc

…

It work for me. If it also works for you I’ll add this step to macos build

Seems that moving ./dist/lib/libtcc.dylib to ./dist/bin/ makes it work,
compile programs successfully, and -run works as well.

So it seems that install target doesn't take everything into account.

Oh, I missed the commits from today.

Indeed, with latest mob (6bd0ced) this now succeeds:
./configure --disable-static && make && make test

However, when building and installing like this:
./configure --disable-static --prefix=$(pwd)/dist && make && make test && make install

Then it succeeds, but the tcc binary seems missing the dylib:
$ ./dist/bin/tcc
dyld: Library not loaded: @rpath/libtcc.dylib
Referenced from: /Users/avih/dev/tcc/tcc.upstream/./dist/bin/tcc
Reason: image not found
Abort trap: 6

When not using --disable-static, then tcc runs fine, compiles and even -run works.

The fix is “macos: tcc searches for libtcc.dyln in the same directory as its executable”

What's the fix? I tried looking at the earlier messages, but didn't
see a diff/patch.

For me on osx 10.13 (real MBA) I also have the same issue when
using --disable-static, but it seems fine without it, including -run.

Yes, it works fine here on my emulated macOS.

Ciao,
