[Bonmin] Fw: BonMin linking errors

[Tony Kelman]

Ujwal,

Thanks for letting us know you got it working. I don’t think there’s any other forum on Bonmin aside from this mailing list. If there’s information elsewhere on the internet aside from COIN-OR pages/Trac/lists that pertains to Bonmin troubleshooting I’m not aware of it.

-Tony

Hi All,



I could figure this out.



I had missed -c options in my CFLAGS.

Subject: BonMin linking errors 

Hi All,



I am trying to link my C++  code with the Bonmin libraries and I have used the following lines in my Make file:

ADDINCFLAGS = -I$(HOME)/MyCoolPrograms/includeCXXFLAGS = -O3 -pipe -DNDEBUG -pedantic-errors -Wimplicit -Wparentheses -Wreturn-type -Wcast-qual -Wall -Wpointer-arith -Wwrite-strings -Wconversion -Wno-unknown-pragmasCXXLINKFLAGS =  -Wl,--rpath -Wl,/home/me/Coin-Pkg/libas described in



https://projects.coin-or.org/BuildTools/wiki/user-examples#LinkingyourCodewithCOIN-ORLibraries



I am using a g++ compiler on UNIX enironment.



While I first included  "-pedantic-errors" , I got the following error 




comma at end of enumerator list



and as I was using someone else's headers, I had to remove this flag.



I tried compiling after removing the above flag and the below are the typr of errors I am getting:



1) usr/bin/ld: /usr/lib/debug/usr/lib/x86_64-linux-gnu/crt1.o(.debug_info): relocation 0 has invalid symbol index 10

2) /usr/lib/gcc/x86_64-linux-gnu/4.6/../../../x86_64-linux-gnu/crt1.o: In function `_start':
(.text+0x20): undefined reference to `main'

3) DesignMain.cxx:(.text+0x12): undefined reference to `Cell::CellGetXpos()'

4) collect2: ld returned 1 exit status



Note: Regarding error (3), my code was compiling fine before including the Bonmin libraries.





Please let me know if I am missing anything basic here.



Also, Could you please let me know if there were already existing forms on Bonmin because, people would have faced similar errors and I could get my answers in the forum discussions ?



Thanks in advance for your help.
