free(): invalid pointer in FamiTracker #75

I don't see anything wrong with what you're doing. When you say "all subprojects" what do you mean exactly? The only subprojects FamiTracker or FamiPlayer need are libfamitracker.so and librtmidi.so. |

Sorry for the vagueness. With this build script in mind, I considered NESICIDE, NES Emulator, FamiTracker and FamiPlayer as this repo's subprojects. Lines 19 to 26 in 9d0845c I only did the |

This helps. I've pushed a fix relative to this breadcrumb:

I'll see about trying this on a more common Linux distro like Ubuntu.
Assuming this is generally supposed to be working, maybe the code just
doesn't like something about my esoteric system.

I tested the new commit, same errors and backtraces as before. |
|
FWIW compiling & running on Ubuntu 18.04 (over the network) launches just fine.
I put a breakpoint in Local buildUbuntu buildEdit: The Ubuntu 18.04 machine has Qt 5.9.5, my local machine has 5.12.10. Copying the Ubuntu build's binary & libraries to my local machine and relinking everything against my system libraries makes it launch properly. Stepping through, it doesn't hit the detach code. I guess this is a problem with the build then and nothing that's weird at runtime? |
|
I had a hunch and tested various versions of GCC. GCC 6 and GCC 7 produce binaries that launch fine, GCC 8 and higher seem to cause these launch failures. Ubuntu 18.04's default compiler is GCC 7.4 hence the builds worked fine there, my distro's default compiler is GCC 10. |
|
Thanks for the investigation help! I'll have to take a closer look at the traces you sent. At a glance it seems there's something wrong with the waveform window's Y position. |

After working around #73 with some dirty patching of the project files I've successfully built & installed the project in build/famitracker. Upon launching, it prints the following and aborts with
SIGABRT:(Click for debugger backtrace)
I'm still messing around with this repository. As a test I ran only the following for now:
Please let me know if this is not a supported way of installing/running the application, e.g. if building & installing all subprojects is required for the binary to function.
