Visual Studio C++ 2010, problem build new version.

[Isith]

Hello,
I have problem with build game using MS VS C++ 2010.
I got following errors :

Code: Select all

content_cao.cpp(1089): error C2668: 'fabs' : ambiguous call to overloaded function
          C:\Program Files\Microsoft Visual Studio 10.0\VC\include\math.h(565): could be 'long double fabs(long double)'
          C:\Program Files\Microsoft Visual Studio 10.0\VC\include\math.h(517): or       'float fabs(float)'
          C:\Program Files\Microsoft Visual Studio 10.0\VC\include\math.h(118): or       'double fabs(double)'
          while trying to match the argument list '(bool)'
content_cao.cpp(937): error C2668: 'fabs' : ambiguous call to overloaded function

          while trying to match the argument list '(bool)'

I building without openal, gettext.
Thanks for help

Okay, i've fixied it to chanage to "double", but i have new problem, my compiled game does not loading chunks.
Can anyone help me to fix it ?

[jn]

I see three trees, some stone, and some dirt; what am I supposed to see?

[Isith]

Game loading chunks but it are very slow like one chunk 5 minutes, digging block shows in debug after 2-3 min, is there any way to make it faster like Celeron builds ?

Sounds like a mod is lagging you.

[Isith]

I downloaded VS Proffesional and compiled in it, can lagging this ? "if(double(m_prop.automatic_rotate > 0.001)){" I ve chanaged fabs to double but i cant build. Here is my recompiled with sound in VS Pro 2010, still lags.

fabs is function, double is a type, please undo this change it doesn't make sense (sorry). And fabs(m_prop.automatic_rotate > 0.001) doesn't make much sense either: You check if m_prop.automatic_rotate is greater than 0.001, the result is a bool (a truth value, true or false), and then you try to cast this bool back into a floating point type, which should not make sense. You probably meant to write something like this (note the parentheses):

Code: Select all

if(fabs(m_prop.automatic_rotate) > 0.001)

This line now checks whether m_prop.automatic_rotate is less than -0.001 or greater than 0.001.

(In this post "you" can refer to either you, Isith; the programmer who wrote the code we're taking about; or anyone else who's interested in this discussion. C++ is hard, it took me quite some time and at least one book to learn it)

[Isith]

But if i undo this chanage, VS have errors in math.h.

Code: Select all

content_cao.cpp(937): error C2668: 'fabs' : ambiguous call to overloaded function
          C:\Program Files\Microsoft Visual Studio 10.0\VC\include\math.h(565): could be 'long double fabs(long double)'

          C:\Program Files\Microsoft Visual Studio 10.0\VC\include\math.h(118): or       'double fabs(double)'
          while trying to match the argument list '(bool)'
content_cao.cpp(1089): error C2668: 'fabs' : ambiguous call to overloaded function

          while trying to match the argument list '(bool)'

And i can't fix it, only double helped to compile code.
Any fix for fabs in VS ?

[jn]

Where can I find the source code you're trying to compile?

[Isith]

ZIP package from Github

[jn]

This problem should be fixed in a newer version, and there are pre-compiled packages on github now.

[Isith]

Ok, now all build fine, but still is so slow, any fix ?

[Isith]

Here is debug :

[Jordach]

You have slow PC:

Code: Select all

12:43:58: INFO[ServerThread]: WARNING: active block modifiers took 2825ms (longer than 200ms)

[Isith]

But it's only on my build, Celeron builds works very fast.
What im doing wrong ?

[Jordach]

Nothing, it just could be something else, maybe a configuration with CMAKE, I've tried compiling and it is really slow, I just think celeron does his builds right, and, if you need latest Windows builds, ask Sfan5: http://minetest.net/forum/viewtopic.php?id=1523

[Isith]

Okay, thanks, i will try to build it with GCC on Linux.

[Jordach]

Use buildbot.sh remember to have these two files in the buildbot.sh directory openal_stripped.zip and mingwm.dll
