Start failed after build on archlinux with segmentation (core dumpbed) #411

NeodarZ · 2016-06-30T19:24:30Z

I tried to build heekscad with this method command :

$ export CASROOT=/opt/opencascade
$ mkdir -p build
$ cd buid
$ cmake -DCMAKE_INSTALL_PREFIX=/usr ..
$ make DESTDIR="$pkgdir/" install

But when I would start heekscad, I see this error :

21:02:06: Warning: Mismatch between the program and library build versions detected.
The library used 3.0 (wchar_t,compiler with C++ ABI 1009,wx containers,compatible with 2.8),
and your program used 3.0 (wchar_t,compiler with C++ ABI 1010,wx containers,compatible with 2.8).

09:02:06 PM: Debug: Adding duplicate image handler for 'PNG file'
Attempt to automatically load HeeksCNC: /usr/lib/libheekscnc.so
[1] 14388 segmentation fault (core dumped) heekscad

So I do not see what to do to successfully built it properly for start it... Can you help me please ?

The text was updated successfully, but these errors were encountered:

A debug trace could help :-)

Nevertheless, the warning could point the problem :

Mismatch between the program and library build versions detected.

and your program used 3.0 (wchar_t,compiler with C++ ABI 1010,wx containers,compatible with 2.8).

@matael Does it work now under Arch ?

No sadly it does not.

Ok now this is strange. With the two lines commented as shown above it now starts every second time.

jb36 · 2017-01-20T10:26:33Z

I just tested again and I needed to specify the C++98 standard to get it working. I'm not sure that this is the best way to do it, but here are the changes that I made.

greyltc · 2017-02-15T13:46:43Z

Strange, I was having these segfaults on Arch Linux too and rather than
set( CMAKE_CXX_FLAGS "-std=c++98" ) as above, I had to do set( CMAKE_CXX_FLAGS "-std=c++11" ) to get things working.

neomilium · 2017-03-26T22:58:40Z

Maybe it related to flags that have been used to compile wxWidgets.
@greyltc , @jb36 could you check this ?

jb36 · 2017-03-27T19:30:19Z

Now Arch has moved on to wxWidgets version 3. That does need the c++11 flag to build. I have tried it only briefly, but was able to create a simple sketch.

The version that I am actively using was compiled with wxWidgets version 2.8. Doing this with both 3.0 and 2.8 installed means running:

cmake -DCMAKE_INSTALL_PREFIX=/usr -D wxWidgets_CONFIG_EXECUTABLE:FILEPATH=/usr/bin/wx-config-2.8 .

For the flags used to compile wxWidgets, I used the PKGBUILD from here: https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=wxgtk2.8

$ pacman -Q wxgtk2.8
wxgtk2.8 2.8.12.1-6

l29ah · 2017-05-30T00:15:51Z

Got the same problem on Gentoo on wxWidgets-3.0.

l29ah · 2017-08-27T03:30:32Z

Ok, the problem boils down to wxWidgets and heekscad being built w/ different C++ compiler{, version}s.

matael · 2017-09-03T20:49:12Z

I got a working binary using this PKGBUILD on an up-to-date Arch for heekscad:

I have no idea how you managed to get something working. Using swig somehow I guess. The error arises in
https://github.com/Heeks/heekscad/blob/master/src/propgrid.cpp#L714-L727 when the if test is bypassed by the compiler (a reference is assumed never to be null).
But somehow this line manages to generate null references https://github.com/Heeks/heekscad/blob/master/src/propgrid.h#L424

Looking at the code, it seems that with SWIG and WXPYTHON, we can avoid most of these issues.

@neomilium, @danheeks Any idea on the best way to get SWIG defined ? Or to compile with swig ?
