Can anyone help mi with compiling source from svn branch on Mac?

[Ivan]

This error was fixed in svn two days ago. Try updating your source code - currently everything works fine (revision 2183).

Hi, I am able to configure but get this error message when running make:

Making all in lib

make[1]: *** [all] Error 2
make: *** [all-recursive] Error 1

I particularly don’t get the ld: message. I assume I am missing a library, but it doesn’t tell me which. Is there a more verbose option? or something that i might need other than what is mentioned in README.linux?
also has anyone been successful in building for OS X?

thanks for your help

A warning and an error:

Also, in the same place, mergable should be spelled mergeable.

It is a bug, a temporary is passed as an output argument for a function. I’ll fix this soon.

EDIT: Fixed in r2586.

[Tow_dragon]

Since last Ivan’s commit (r2871) I cannot compile VCMI on my OpenSUSE:

VCAI.cpp: In member function 'bool VCAI::tryBuildStructure(const CGTownInstance*, int, unsigned int)':
VCAI.cpp:1270:33: error: 'class CTown' has no member named 'buildings'
VCAI.cpp:1285:31: error: 'class CTown' has no member named 'buildings'

“make clean” does not help. Including CTownHandler.h in VCAI.cpp produces even more bizarre and inexplicable errors. Any ideas?

[Ivan]

“make clean” does not removes precompiled headers (.gch files). And it looks that AI/VCAI/StdInc.h includes most of library headers (bad idea I think - our lib headers change quite often).

Removing AI/VCAI/*.gch file should fix this.

I usually use CMake + Clang - works twice faster compared to autotools + gcc without bizarre bugs like this.

[Tow]

bad idea I think - our lib headers change quite often

Bad idea when you work on lib part; good idea when you are working on the AI part only, as I did for quite a while. I however I don’t anymore, lib includes in PCH can go. And they should if they cause trouble for make/gcc users.

[Tow_dragon]

I thought about PCH, but I assumed that make clean removes them. Strange behavior.

What should I do to switch to Clang? Does it produce reasonable debug info for gdb? Currently I’m trying to set up development environment on Linux to familiarize myself with it but it’s more time consuming than I thought. I assumed that make install does something different than placing symlinks in appropriate places and now I’m discovering what should go where – and apparently it changed since I last run VCMI under Linux, about a year ago.

[Tow]

What should I do to switch to Clang?

Calling configure (or cmake) with environment variables CC=clang CXX=clang++ should suffice, at least it once did for me AFAIR. You’ll need a Clang 3.1 that was released in May (or svn build).
I believe it should work with GDB just like GCC.

[Ivan]

PCH work somewhat weird: sometimes make will recompile them, sometimes it will not.
And I haven’t found any way to fix them except for removing. I left PCH because system headers are not likely to change.

What should I do to switch to Clang?

VCMI needs latest clang (3.1) and at least boost 1.48 - higher version than gcc due to bug in boost.
Debug info with clang looks to be on the same level as gcc - I assume that it can be described as “reasonable”.

To use it with autotools rerun configure:
CC=clang CXX=clang++ /configure

With cmake:
CC=clang CXX=clang++ cmake -DCMAKE_BUILD_TYPE=Debug

I assumed that make install does something different than placing symlinks in appropriate places

It does actual installation - copies all binaries to install path.
All symlinks should be placed manually. Maybe I should add something like “make symlinks” to cmake?
Symlinks that I have created for cmake:

.../bin/vcmiserver             -> .../build/server/vcmiserver
.../lib/vcmi/AI/libStupidAI.so -> .../build/AI/StupidAI/libStupidAI.so
.../lib/vcmi/AI/libVCAI.so     -> .../build/AI/VCAI/libVCAI.so
.../lib/vcmi/libvcmi.so        -> .../build/lib/libvcmi.so

Autotools uses a bit different directory structure - binaries are in hidden subdirectories. For example path to client will be
/client/.libs/vcmiclient
