5 years ago Hi @eminarcissus
Thanks for your PR!
Already reported https://github.com/xiangzhai/dragonegg/issues/23
Workaround for Linux https://github.com/xiangzhai/dragonegg/commit/2736f2a735244ca3ab029ac06456140c4217e6f5
So you could simply workaround it for __unix__.
Cheers, Leslie Zhai

5 years ago Wow, thx very much. Sorry didn't noticed that issue That did works out, but some few other issues looks like here. cc1: fatal error: plugin ./dragonegg/dragonegg.so is not licensed under a GPL-compatible license dlsym(0x1439039e0, plugin_is_GPL_compatible): symbol not found
I will check where's the problem here :)

5 years ago quite weird, no matter if I define it as 1 or 0, or just comment out this out, all comes up with the same error. looks like is gcc itself trying to check for this value when loading a plugin?

commented
5 years ago https://github.com/gcc-mirror/gcc/blob/master/gcc/plugin.c#L712
so workaround might be:
int plugin_is_GPL_compatible __attribute__((visibility("default"))) { return 0; }looks like the problem roots from CPP naming conventions. this is the result after I decompile the so file. symbol plugin_is_GPL_compatible is being compiled to _plugin_is_GPL_compatible as global variable. Didn't confirmed yet.

5 years ago You could just comment the Check the plugin license https://github.com/gcc-mirror/gcc/blob/master/gcc/plugin.c#L711
And rebuild gcc https://github.com/xiangzhai/dragonegg/wiki/GGC#fedora-25

5 years ago yeah... that probably works out, will try it now 👍

5 years ago quite devastating problems here looks like. after comment out this line now GPL check works out but plugin_init not found. dlsym(0x141f05980, plugin_init): symbol not found I've tried to remove the leading underscore but still no help(by adding asm("plugin_init") when defining the function).
Also double checked dragonegg.so compiled with GCC4.8 and llvm3.5. Looks like both GPL license check and plugin_init are pre underscored. So I believe this might be some other problems here. Don't know how to start on debuging this kind of problem...

5 years ago plugin_init could not be commented :)
What about this commit? https://github.com/xiangzhai/dragonegg/commit/d332eefb270555b2b46919171ab59073d66ea4a3

5 years ago didn't work out. Also that commit looks like is a fix for GCC 4.9.3? The error itself looks really obscure, 000000000000c3d3 l F TEXT,text __ZL13version_checkP18plugin_gcc_version 000000000000c3f4 l F TEXT,text _plugin_init 000000000000d1a4 lw F TEXT,text __ZN4llvm4castINS_8ConstantEKNS_5ValueEEENS_10cast_rettyIT_PT0_E8rettypeES7
and plugin.c just calling dlsym(handle,"plugin_init"), so it shouldn't be a error telling symbol not found, quite confusing.

You could try @my-HenryS `s workaround https://github.com/my-HenryS/dragonegg/commit/3252c914c2741147fc52002bbda78d6f432bcfc2#diff-b67911656ef5d18c4ae36cb6741b7965

5 years ago Quite weird, after patch Henry's version it is not even building, I saw some header files change which like Target -> CodeGen which is not exists with llvm-6.0, Also some errors like this

5 years ago I don't know if it is really a gcc compiling problem or not, because I did have gcc compiled with plugin and the compiling dragonegg versions don't have too structural difference in code(the latest master the 2017 latest version). They both contains debug_tree in the same function at a first glance. More changes were taken in header files, which I guess is accommodates different version of llvm and gcc, but older one works but not the latest one. Except for debug tree(I tried to comment out that line first for a compile), there are also some other problems as well, I'm considering to build a llvm-9 to give it a try as well.
For the debug_tree problem, the same thing happening when I compile the old version dragonegg with different version of llvm(especially for the latest working version between llvm3.2 and dragonegg3.2, a small version bump might create quite a lot similar problems).

5 years ago hmmm,llvm-9 is not officially released yet?
Hi,
Thanks very much to make this project continued til now :) I'm now trying to compile it on OSX with GCC6.4 and llvm-r311142. I've checkout to the c1b5b35 commit which I believe is the repo which should worlks with GCC6 and llvm this version.
Currently the code is compiling, and successfully linked. But somehow it yields out this error when I tried to do a fplugin compile.
gcc-6 a.c -S -O1 -o - -fplugin=./dragonegg/dragonegg.so -L/usr/local/llvm-6 cc1: error: cannot load plugin ./dragonegg/dragonegg.so dlopen(./dragonegg/dragonegg.so, 10): Symbol not found: _C_alloca Referenced from: ./dragonegg/dragonegg.so Expected in: flat namespace in ./dragonegg/dragonegg.so
Any hints would be real appreciated :) Now I'm trying to compile some fortran codes with dragonegg, so I have to keep a backup system for years ago. It would be really helpful if this does working here :)
Attached is gcc6 compile info.
