FiveHGC.lib - Undefined reference ot _Unwind_Resume
Posted: Tue Aug 30, 2016 07:12 AM

Hi, all.

When linking my application, I get the following error:

/fwh.2012.04/lib/fivehgc.lib(ACTX.o):ACTX.CPP:(.text+0xe08): undefined reference to _Unwind_Resume' /fwh.2012.04/lib/fivehgc.lib(ACTX.o):ACTX.CPP:(.eh_frame+0x2b7): undefined reference to__gxx_personality_v0'

I recently upgraded to the nightly build of Harbour (3.2.0dev r1608101712), which resulted in this error. I am linking FWH 2012-04 build. Is there a lib binary for the latest Harbour/MinGW? Should I upgrade to latest FWH?

Thanks

After updating Harbour with the nightly build and a day of walking in circles without getting anywhere seeking the solution to this problem, I finally figure out that MinGW GCC have 3 different "Exception handling" systems: SJLJ, DWARF, and SEH.
Harbour nightly build was using SJLJ version:

Code (fw): Select all Collapse

gcc --version
gcc (i686-posix-sjlj-rev0, Built by MinGW-W64 project) 5.3.0

and DWARF one was needed.
In my case I looked for the very same version:

gcc --version
