[re-unsolved] Mingw compiling problems

[Lord Aro]

Nope, still doesn't work - i'm going to recon that it's becaus of the lack of admin rights
/me gives up (for now)

[oberhümer]

I don't think there are any admin rights in MSYS, do you mean on the computer itself?
That shouldn't be a problem, I managed setting up my complete MinGW environment using a computer on which I had none.

...So what exactly is going on this time?

[Lord Aro]

same error as before...

[Tafidis]

There seems to be an issue with the compilation of xz. I have added some comments on the relevant wiki discussion page.

Basically, if you follow the instructions in the guide about unpacking the files in your home folder without using wget, unzip etc from the command line, the xz package does not compile properly (lzma does not get installed). You don't get any (obvious) error messages, but when you try to compile openttd it fails. Actually, ./configure reports that lzma was not found but you can nevertheless install openttd, which is clearly not the case as a makefile is not created. I believe it has to do with the dependencies (gettext-runtime, glib, pkgconfig) which I believe need to be installed in a different folder.

Everything works fine if you use the command line method of unpacking

[Eddi]

you probably skipped the end of that sentence where it says you have to give a parameter to configure to continue without lzma.

[Terkhen]

I heard about a problem like this one already. The person with the issue forgot to edit his etc\fstab, as described here: http://wiki.openttd.org/Mingw#Setting_up_MSYS

[Tafidis]

@Terkhen: I did edit fstab. I followed the guide exactly. Also the link for pkgconfig in the list of required packages is broken.

Further down, under "compilation and installation of the required packages" the guide prompts you to install msys-wget, msys-unzip and msys-patch. Right below, it says: "alternatively, to the wget/unzip steps ... ". This did NOT work for xz package. I believe it has to do with the dependencies (gettext-runtime, glib, pkgconfig) which are unzipped using /mingw argument (when using shell commands). Because what I did to solve this was to copy the downloaded (compressed) packages to the home folder and use the shell commands to unzip and install (instead of just extracting using 7-zip in windows).

[Terkhen]

That alternative looks quite outdated. In the xz prerrequisites case, you need to unzip them to the correct folder or they will not work (or copy them after extraction, but that is not mentioned in the tutorial). Since it is confusing to mention two methods I have just removed the "alternatively" line from the tutorial.

Regarding your comments on the Talk page: it is possible to compile OpenTTD without lzma support using ./configure --without-lzma. It is not a great idea, because then you will not be able to load savegames saved with lzma or connect to servers that use lzma. Check the readme for details.

[Tafidis]

Well, you can still download the packages from the links and copy them to the home folder, and then use unzip command lines as instructed in the page to copy them to the correct folder (which is what I did). Also, the alternative method works fine with all other packages.

But I agree with you it is confusing to mention two methods

[noodless]

So how do we get the lzma files to work as they should, noting I followed the command-line manner of unpacking things?

[Terkhen]

In theory, by following the tutorial line by line. Did you do anything different? Did you get any errors while installing any of the libraries? What error are you getting with lzma?

[noodless]

'lmza was not detected or disabled' ; I followed every direction word-for-word too.

[Alberth]

that's what OpenTTD says, right?

that means it cannot find lzma.
Assuming you did install that library, where did you install it, did you get any wanrings or errors there, how did you install it?

Edit: In other words, we need DETAILS before we can help you. Something as small as a single letter typo can make a difference. How exactly did you do each step of the way. What did the computer report? We cannot read what you typed at your computer to verify your conclusions.

[Terkhen]

Strange, it is the second time I get a report like this one... Tomorrow I'll uninstall MinGW and repeat the tutorial to test if something changed.

EDIT: Getting the answers to Alberth's questions will help when I check this

[Tafidis]

'lmza was not detected or disabled' ; I followed every direction word-for-word too.

You probably forgot /mingw argument when unpacking the prerequisites for the xz package (last one in the tutorial). I had the same problem.

Check the command lines for the xz package more carefully.

[noodless]

While compiling, now I have this error to do with the ai_config.CPP file.

[Terkhen]

I checked the tutorial completely and updated some parts of it. The liblzma part did not require any updates and worked fine for me.

noodless: You moved from the libzlma issue without mentioning if you managed to fix it... Please give complete explanations of what you do, otherwise we won't be able to help you.

Is liblzma now being detected correctly by your OpenTTD configure? Or did you just compile without liblzma?

Also, judging from your screenshot, your home folder for MSYS is located at your desktop folder. If you followed the tutorial line by line, your home folder should be in C:\MinGW\msys\1.0\home\username. The other person which had problems with compiling liblzma also had his home folder in a location different from the standard one. My guess is that both of you have installed something that messes up with MinGW/MSYS default directories by redefining folder location via environment variables or registry keys. I have no clue of what program might be causing this issue, though.

Yes, I went back and modified the file in etc so now it reads the liblzma files.

I had already taken the privilege of updating the link to pkg-config, but it seems it wasn't needed after all. And why did you remove the 'don't panic' part?

My guess is that both of you have installed something that messes up with MinGW/MSYS default directories by redefining folder location via environment variables or registry keys. I have no clue of what program might be causing this issue, though.

I think it is because when MinGW is installed onto the desktop there are spaces in the path name, which causes the pathname string to terminate earlier than expected (at the space) and take the rest as a parameter or something. I believe 'the other person' has also done something similar.

EDIT: noodless: I just saw your screenshot (I hadn't logged into ImageShack), spaces aren't the problem, maybe it is something else.

[ChillCore]

While compiling, now I have this error to do with the ai_config.CPP file.

Code: Select all

[src]Compiling ai/ai_config.cpp
...

There is absolutely nothing wrong with the ai files, the problem you are having is not there but in src/settings_type.h which is included in src/ai/ai_config.cpp (line13).
Your source is patched and you bumped without solving the conflicting code before compiling?

"<< ..." at line 406 is the start of the unsolved conflict,
"== ..." at line 408 is between the codeblocks you need to merge.
">> ..." at line 410 is the end of the conflict.

Depending on what changed in trunk you need to either:
- keep line 407 and get rid of 409.
- keep line 409 and get rid of 407.
- merge line 407 and 409.
- keep line 407 as line 407 and move 409 to its correct location.
- keep both lines ...

Compare the patch you applied with current clean trunk and it should become clear what you should do.
Lines 406, 408 and 410 should be removed after solving the conflict and before compiling.

ps:
After solving this conflict there may be others but ai_config.cpp should compile if you did the correct thing.
