My goal is a mod that will include various extra assets when certain combinations of mods/DLCs are present, but without having any of these as a "hard" dependency. I've been using #if __has_include() ... #endif to accomplish this for the simplest situations like the following config.cpp structures, which work fine...
...in these examples, I'm trying to avoid having the CSLA CDLC, and the GMX Takistan and GMX ChDKZ mods as "hard" dependencies...
class CfgPatches {
<some code>
};
class CfgVehicles {
class O_MBT_02_cannon_F; // or any classname from a "hard" dependency
#if __has_include("\gmx\gmx_tak\gmx_tak_core\data\gmx_tak_icon_ca.paa")
class my_tak_mbt : O_MBT_02_cannon_F {};
#endif
#if __has_include("\gmx\gmx_chdkz\gmx_chdkz_core\data\logos\gmx_chdkz_logo_ca.paa")
class my_chdkz_mbt : O_MBT_02_cannon_F {};
#endif
};#if __has_include("\csla_cfg\images\logos\csla_dlc_logo_ca.paa")
class CfgPatches {
<some code>
requiredAddons[] = {"CSLA"};
<some more code>
};
class CfgVehicles {
class CSLA_T72;
class my_t72 : CSLA_T72 {};
};
#endifHowever, if the extra assets are dependent on more than one of these "soft" dependencies, then I get the following error message on startup.
Preprocessor failed with error - invalid filename(empty filename)
Here's an example of dual "soft" dependency which results in the error...
#if __has_include("\csla_cfg\images\logos\csla_dlc_logo_ca.paa")
class CfgPatches {
<some code>
requiredAddons[] = {"CSLA"};
<some more code>
};
class CfgVehicles {
class CSLA_T72;
#if __has_include("\gmx\gmx_tak\gmx_tak_core\data\gmx_tak_icon_ca.paa")
class my_tak_t72 : CSLA_T72 {
<change faction, crew, etc. to gmx_tak>
};
#endif
};
#endif...And for good measure, I tried adding an #else statement, hoping it might force the first #if to step over the second #if; but it still errored.
#if __has_include("\csla_cfg\images\logos\csla_dlc_logo_ca.paa")
class CfgPatches {
<some code>
requiredAddons[] = {"CSLA"};
<some more code>
};
class CfgVehicles {
class CSLA_T72;
#if __has_include("\gmx\gmx_tak\gmx_tak_core\data\gmx_tak_icon_ca.paa")
class my_tak_t72 : CSLA_T72 {
<change faction, crew, etc. to gmx_tak>
};
#endif
};
#else
#endif
