Michael, it probably works for you because your system is set
differently. Mine is 'standard" I mean installed wo. special tuning.
--- Makefile ---
ifndef TOP
TOP = .
CURDIR = $(PWD)
SYSTEM = `uname`
endif
export DYLD_LIBRARY_PATH := $(CURDIR)/$(TOP)
export DYLD_LIBRARY_FOO := $(CURDIR)/$(TOP)
export DYLD_FOO_PATH := $(CURDIR)/$(TOP)
export DYLDFOO_PATH := $(CURDIR)/$(TOP)
export EDYLD_LIBRARY_PATH := $(CURDIR)/$(TOP)
export
all:
@echo Running on $(SYSTEM)
@echo in Makefile environment is set to
@set
$ make | grep DY
DYLDFOO_PATH=/Users/jullien/foo/.
EDYLD_LIBRARY_PATH=/Users/jullien/foo/.
All "^DYLD_" variables are dropped!!!
I'll revert to the code I wrote which uses "DYLD_LIBRARY_PATH=<tcc-path> tcc"
I faced a similar issue while porting Le-Lisp (not OpenLisp) on macOS. The
assembler code has dlink and llink variables (dynamic and lexical link). macOS
assembler uses llink internally and silently dropped (wo warning) this variable
while dlink was kept (!). It took me 2 days to understand. Grrrr!

Thank you for testing, make is the same:

Single dash was an automatic edit from my email agent. I pass of course 2 dashes
I tested on High Sierra which uses bash and Catalina which uses zsh. It fails
the same on both systems.

Hello,

It is still unclear why it does not work but on macOS, ./configure

Hmm, can't reproduce here:
% git log -1 --online HEAD
9d75f14 Fix structure passing i386 PE
% make clean
% ./configure --disable-static
...
Config OSX static=no
...
% make
% make test
... works ...
(Note the double dash for configure options, I'm not sure if it was just a typo
in your mail). And there's proof that the export from the Makefile does work,
because calling tcc from the tests directory directly indeed doesn't work:
% cd tests; ../tcc -h
dyld: Library not loaded: libtcc.dylib
Referenced from: /Users/micha/src/tinycc/tests/../tcc
Reason: image not found
Abort trap: 6
So that the testsuite works for me is the indication that the 'export
DYLD_LIBRARY_PATH' construct does work (for me). Any differences in make
behaviour perhaps?
