iOS C++ fails on virtual function check

G++ fails on virtual function check



Google tells me nothing

Does G++ on iOS not support virtual functions, or am I missing some package, or did something wrong
??

Can you verify that g++ works at all? There is a symlink that you need for g++ to work, there is a package on cydia for it.  Something like libstdc++  Also can you post the the relevant part of config.log?

[grinch]

I made sure I had that lib symlink installed, as well as other libs, but error in log is looking for it. I have reinstalled it, thinking something got messed up, still not working

Code: [Select]

configure:8631: checking if -fno-implement-inlines implements virtual functions
configure:8668: g++ -o conftest  -O2 -Wall -Wwrite-strings -Woverloaded-virtual -fno-exceptions -fno-rtti -fno-implement-inlines   conftest.cpp  >&5
ld: library not found for -lstdc++
collect2: ld returned 1 exit status
configure:8668: $? = 1

That indicates that the library/symlink isn't setup correctly, no doubt about that. 

[grinch]

Yeah I'm not sure whats wrong. Reinstalled it, still does not work

[Trcx528]

Try making a copy of libSystem as /usr/lib/libstdc++.dylib and see what happens with that, otherwise I would trying doing a find and replace and remove -lstdc++ from configure&Makefile

[grinch]

Could not copy at first bc of the symlink. I removed, made a copy and I was off to the races. Just had a few more dependencies to install

./configure finished created makefile, but make failed. Too late for me to look into it, so it will be another day

Code: [Select]

unistd.h:705:28: error: crt_externs.h: No such file or directoryLooks like some missing header, from someplace, not sure yet

[A12danrulz]

Try putting this in /usr/include/

[grinch]

Solved that. Now I have a new error, will post if I get stumped

I've got an onion now

After adding file after file from Apples opensource library, it was looking for __config. I added it from apple, and inside apple file, it is listed as "for Windows NT". Now its looking for windows.h and asking me to define _WIN32_WINNT, as well as having non-fatal issues with the cstddef.h I got from Apple

[A12danrulz]

Did you try downloading windows.h?

[grinch]

No I have not. I get wary about adding windows anything, this is a small linux program, it does not need or use anything from windows. Its the apple headers that call for windows bologna
