compilation errors: BONMINLIB_EXPORT and bad ld name

[BrannonKing]

When I try to compile Couenne I get this error:

./../src/main/CouenneBab.cpp:45:8: error: ‘BONMINLIB_EXPORT’ does not name a type; did you mean ‘COUENNELIB_EXPORT’?
   45 | extern BONMINLIB_EXPORT Bonmin::OACutGenerator2 *currentOA;   // pointer to the OA generator

My OS is a fairly recent version of Manjaro. Also, the build file should specify the required C++ standard. There are a lot of warnings when compiling with C++17 (the default on my machine). If I switch the export macro to the suggested one, it still doesn't fully compile for me. It fails at the very end with this error:

As a sidenote, when I attempt to install Couenne from the AUR, I get a compilation error about missing asl.h, although I have plenty of them on my system.

BONMINLIB_EXPORT should be defined in BonminConfig.h, which should be included by some of the Bonmin headers that is included by CouenneBab.cpp. As there is no information on how you try to compile Couenne, I can just guess that maybe you build against an old Bonmin version that doesn't fit to the Couenne version you try to compile.

I also get plenty of warnings about the deprecated use of register when compiling Couenne. So far, I choose to ignore them.

I cannot say why libCouenne.so is missing. There is

 CXXLD    libCouenne.la

which should have create them. Do a make clean and call make with V=1 to get more output.

@BrannonKing, I wrote a comment on the aur page of coin-or-couenne which allows you to compile the package. It was looking in the wrong folder for the asl.h and later had issues with the c++ standard version. With the patch posted below I am able to compile and install the package. For people stumbling over a problem with the c++17 standard I was able to compile it with -std=c++11 in the CXXFLAGS until the code is adapted to the new standard.

@BrannonKing have you solved it?
I am compiling it via git clone & I face same issue
