Compile Help?

[AndHobbes]

With the instructions in the pinned post and some trial and error, I was able to get the game to compile and launch the latest stable pak128.Britain-Ex.  However, the application crashes when clicking Load Game.

I'm getting an error in loadsave_t::rd_open on this line:

Code Select Expand

if(  BZ2_bzRead( &fd->bse, fd->bzfp, buf, sizeof(SAVEGAME_PREFIX) )==sizeof(SAVEGAME_PREFIX)  &&  fd->bse==BZ_OK  ) {
The error is "An invalid parameter was passed to a function that considers invalid parameters fatal."

Hello - sorry that you are having trouble. May I ask what platform that you are using?

[AndHobbes]

Windows 10 64-bit.  I downloaded all dependencies in 32-bit and am compiling for Win32 target in Visual Studio.

[jamespetts]

Ahh, yes, I have not set up 64-bit compilation for Windows yet, although I may have to do so soon as memory requirements for large maps may be enough to require 64-bit code. You can always use the pre-compiled executable for Windows if you cannot get it to compile yourself.

[AndHobbes]

I am compiling a 32-bit executable (Win32 build target in Visual Studio), it's just the operating system that's 64-bit, which shouldn't be a problem.

The debug build launches and runs fine, except for saving and loading games, so I suspect that I may not have the bzip2 dependency referenced correctly.  I downloaded bzip2-dev-1.0.6-win-x86.zip and bzip2-dll-1.0.6-win-x86.zip as suggested here:

https://github.com/philr/bzip2-windows/releases

From those files, I made sure that bzlib.h was in the includes path and libbz2.lib was in the library path, before which it didn't compile.  Then I made sure libbz2.dll was in the same directory as the compiled.exe, before which it didn't run.

[jamespetts]

That is odd. It is difficult for me to check my own arrangement in detail at present, as I am staying away from home for Christmas and thus have no access to my development computer. Are you using the supplied Visual Studio project file? If so, can I check that you are using the correct one - may I ask what the filename of the one that you are using is?

set in simuconf.tab saveformat zipped

Code Select Expand

# compress savegames?
# "binary" means uncompressed, "zipped" means compressed
# "bzip2" uses another compression algorithm
# other options are "xml", "xml_zipped" and "xml_bzip2"
# xml detects more errors of broken savegames but files are much larger
# bzip2 savegames are smaller than zipped but saving/loading takes longer
saveformat = bzip2


I think than save and load savegames

All binaries depend on the Visual Studio 2013 C Runtime Library (msvcr120.dll). This can be installed using the Visual C++ Redistributable Packages for Visual Studio 2013 installer.

the dll-file from page is for VS 2013

No problem, I appreciate the assistance!  I opened Simutrans-Extended.sln which references Simutrans-Extended.vcxproj.  It was correctly opened as a Visual Studio 2015 project, with VS2015 (v140) platform toolset and 8.1 target platform version.

Confirmed that this is set in simuconf.tab:

saveformat = bzip2

[jamespetts]

I can only guess that this is some bzip2 compatibility issue, perhaps a bad version. May I suggest trying the library/dll versions here?

[DrSuperGood]

With exception of PThread, I suggest building your own dependencies. Most have a MSVC compatible build process which requires only minor property changes.
