Sorry for the late reply. This patch works well for macOS Sierra 10.12.6 and also High Sierra 10.13.4.

For having CERTI working with Ptolemy, I need also to execute this command as indicated in $ PTII/org/hlcerti/.build-certi.sh:
sudo sh -c "cd /usr/local/lib; ln -s /Users/j.cardoso/pthla/certi-tools/lib/* ."

An additional comment, it would be great if you can create an account and log in. It's better to keep track on the issues and, for you, to receive any update regarding questions/problems you have.

Best regards,

It seems that there is an issue in CMakeList. Can you please try the following patch "jbch_patch_53954.patch" and see if it works for you.

Can you please mention the quickfix you are talking about?
Is the quickfix from the CMakeList mentionned in your ticket?

Best regards

Under clang 9.1.0 and macOS 10.13.4, clang fails with:

[  9%] Linking CXX shared library libHLAd.dylib
clang: error: no such file or directory: ';-flat_namespace'
make[2]: * [libHLA/libHLAd.4.0.0.dylib] Error 1
make[1]: * [libHLA/CMakeFiles/HLA.dir/all] Error 2
make: * [all] Error 2

How to reproduce:

git clone -b br_jbch_4.0.0 https://git.savannah.nongnu.org/git/certi.git
cd certi
mkdir build
cd build
cmake -DFORCE_NO_X11=ON ..

Here's my OS and clang:

bash-3.2$ uname -a
Darwin ealmac23 17.5.0 Darwin Kernel Version 17.5.0: Fri Apr 13 19:32:32 PDT 2018; root:xnu-4570.51.2~1/RELEASE_\
X86_64 x86_64
bash-3.2$ clang --version
Apple LLVM version 9.1.0 (clang-902.0.39.1)
Target: x86_64-apple-darwin17.5.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

CMakeLists.txt contains the following:

# FIXME currently on MacOS we have a "undefined symbol issue"
# The toggle to linker flag is a "quick fix" to avoid that
# but this is not the end of the story we need to fix it for good.
if (APPLE)
   SET (CMAKE_SHARED_LINKER_FLAGS ${CMAKE_SHARED_LINKER_FLAGS_INIT} "-flat_namespace -undefined suppress"
        CACHE STRING "Flags used by the linker during the creation of dll's." FORCE)
   # module linker flags
   SET (CMAKE_MODULE_LINKER_FLAGS ${CMAKE_MODULE_LINKER_FLAGS_INIT} "-flat_namespace -undefined suppress"
CACHE STRING "Flags used by the linker during the creation of modules." FORCE)

   #set(PROPERTY LINK_FLAGS_DEBUG "-flat_namespace -undefined suppress")

So, it seems like the quick fix only works under certain compilers.
