System module function NID not resolved while loaded

[dmemarko]

App built with libSceAppContent linked crashes when sceAppContentInitialize being called. It's function NID cannot be resolved from module which is actually loaded, as seen from the crash log.

build.bat has lib added:

set libraries=-lc -lkernel -lc++ -lSceVideoOut -lSceSysmodule -lSceAppContent

Actual code:

void initialize_app_content() {
    int ret = 0;
    (void)ret;

    ret = sceSysmoduleLoadModule(SCE_SYSMODULE_APP_CONTENT);
    DEBUGLOG << "sceSysmoduleLoadModule(SCE_SYSMODULE_APP_CONTENT) " << ((ret == ORBIS_OK) ? "ok" : "failed");

    SceAppContentInitParam initParam;
    SceAppContentBootParam bootParam;
    memset(&initParam, 0, sizeof(SceAppContentInitParam));
    memset(&bootParam, 0, sizeof(SceAppContentBootParam));
    ret = sceAppContentInitialize(&initParam, &bootParam);
    DEBUGLOG << "sceAppContentInitialize(&initParam, &bootParam) " << ((ret == ORBIS_OK) ? "ok" : "failed");
}

Extended prototypes in orbis/AppContent.h:

#define SCE_SYSMODULE_APP_CONTENT 0x00b4

typedef uint32_t SceAppContentBootAttribute;

typedef struct SceAppContentInitParam {
    char reserved[32];
} SceAppContentInitParam;

typedef struct SceAppContentBootParam {
    char reserved1[4];
    SceAppContentBootAttribute attr;
    char reserved2[32];
} SceAppContentBootParam;

int32_t sceAppContentInitialize(
    SceAppContentInitParam *initParam, 
    SceAppContentBootParam *bootParam
);

extra info: this happens because the converter does not take into account that prx/lib/module name can all be different. In this case the module is libSceAppContentUtil not libSceAppContent. furthermore a single module can contain multiple libraries. and a nid can have several implementations over multiple libraries in the same module. handling this might be somewhat annoying...

The issue of the module and PRX name being different can be handled, in fact I think we do already handle a few of these cases (though we're missing a few for sure). The case of multiple libraries, yeah this is a royal pain and it's going to be tough to handle :(
