FreeBSD build?

[Peter2121]

I'm trying to build wxHexEditor (cloned from GitHub) on FreeBSD 11 with codeblocks installed.

The project opens correctly, but trying to build it I get many errors about headers lost:

||=== Build: Release in wxHexEditor (compiler: GNU GCC Compiler) ===|
mhash/include/mutils/mincludes.h|34|fatal error: mutils/mhash_config.h: No such file or directory|

Following your Linux procedure in COMPILE, I need to install

wxHexEditor library for compilation

It is not clear at all, no such library is available in your GitHub account.
Both wx28-gtk2-2.8.12 and wx30-gtk2-3.0.2 are installed in my system.

Hi,
error: wx/wx.h
means you don't setup wxGTK properly. Probably you need to install development packages instead of run libs.
"mutils/mhash_config.h" error means you don't compile mhash library first.

Indeed I don't remember how I compile it in FreeBSD.
You might be better using make command after installing wxgtk-devel.

[Peter2121]

There is no *-devel packages in FreeBSD, normal library package installs all the necessary files to compile anything.
I have wx.h in /usr/local/include/wx-2.8/wx and in /usr/local/include/wx-3.0/wx, there are many other *.h files in these dirs.
I'll try with make command.

[EUA]

Himm, probably your compiler path doesn't include /usr/local/include but /usr/include

[Peter2121]

So, I added to my environment:

LD_LIBRARY_PATH=/usr/local/lib
LIBRARY_PATH=/usr/local/lib
CPATH=/usr/local/include

Then I modified in Makefile:
WXCONFIG ?= wx-config
to
WXCONFIG ?= wxgtk2u-2.8-config

Then I try to build it using gmake.
I got compilation errors like this:

src/FAL.cpp:65:12: error: use of undeclared identifier 'DKIOCGETBLOCKSIZE'
        ioctl(FD, DKIOCGETBLOCKSIZE, &block_size);
src/FAL.cpp:85:12: error: use of undeclared identifier 'DKIOCGETBLOCKCOUNT'
        ioctl(FD, DKIOCGETBLOCKCOUNT, &block_count);
src/FAL.cpp:866:13: error: no matching function for call to 'ptrace'
                                        word = ptrace(PTRACE_PEEKTEXT, ProcessID, addr);
src/FAL.cpp:885:50: error: arithmetic on a pointer to void
                        memcpy( buffer, internal_file_buffer.GetData()+from, size );

Himm. They are the real issues. I have to change some locations to make it compatible for FreeBSD.
I will install FreeBSD VM and try to fix them.
Thanks.

[Peter2121]

Thanks for supporting our platform, hope to see wxHexEditor in ports tree one day ;)

[EUA]

@Peter2121 I like to support but ... I think FreeBSD has some issues with KVM/QEMU Xorg VM setups.
I just download X11 qcow image and installed xorg & gnome3. But xorg doesn't want to work...
Any help?

[Peter2121]

As it was mentioned in the forum post, it is really simple to use VirtualBox. There are VB additions that you can install directly from packages on VM, and if you install Oracle VB extensions on the host - even the video acceleration should work correctly on guest VM. I can share a pre-installed VB image if you want.
As I use FreeBSD as OS, I have no experience of using KVM. I know that FreeBSD as guest works fine on VirtualBox and VMware ESXi/Workstation.
As about DE - you should use XFCE or LXDE, that's the most stable DEs on FreeBSD. You can try Lumina too.

Installed using UEFI way. It's Working now.
Also fixed many things and able to compile right now...
But now wxHexEditor gives segmentation fault at startup.
Probably BSD support will updated this night or next.

[EUA]

@Peter2121 I just compiled and got segfault. As I understand segfault not due program because it's before execution of init.
So I decide compile wxWidgets at FreeBSD. Unfortunately, with same result.
When I try to compile & run wxWidgets own samples at samples directory, they also give segmentation error and exit. I don't know what is happening here. I compiled wxWidgets lib for both GTK2 and GTK3 with same result...

[EUA]

I don't know when and why this clang love appeared on BSD but the problem is GCC incompatibility.
After switching to clang, it starts working.
You can compile easily with
gmake WXCONFIG=wxgtk2-3.0-config
old make command make some error on compilation somehow, use gmake please...
Anyway, It's your turn to make beta testing. 👍

[Peter2121]

It seems that there is a problem of library:

$ gmake WXCONFIG=/usr/local/bin/wxgtk2u-3.0-config

/usr/bin/ld: cannot find -lgomp

/usr/local/lib/gcc6/libgomp.so.1.0.0 is present, symlink libgomp.so is present in the same dir
Adding /usr/local/lib/gcc6 to LIBRARY_PATH don't help a lot - there are still OPENMP related errors:

[Peter2121]

OK, I've got it.
One need to install openmp package, the library from gcc6 does not work correctly here.
I can start wxHexEditor and open files, but it crashes trying to create new file:
Floating point exception (core dumped)

[Peter2121]

gmake install is failed:

$ gmake install
install -D -m 755 wxHexEditor //usr/local/bin/wxHexEditor
install: target directory `//usr/local/bin/wxHexEditor' does not exist

(I changed prefix in Makefile, without such modification it tries /usr/bin/wxHexEditor and failed the same way)

[EUA]

I removed the "-D" and it looks working proper now.
Please try again.

gcc issue is true at FreeBSD. Probably due libs... I think it's nothing to do for me.
I just use clang.

[EUA]

Tested with FreeBSD12 and working with instructions.
