| − | *I spend my time today mainly working on the issue of overloaded functions.
| |
| − | *As suggested by the PBG developer(by personnel email), I checked the pybindgen.gccxmlparser module but could not find any issue.
| |
| − | *Later on diging the code of OpenNurbs I found that all the overloaded functions which were causing the issue were private constructors mainly used for singleton pattern
| |
| − | *Also Interestingly all these private constructors didnt have definitions as well.
| |
| − | *Thus I removed them manually from the auto generated c++ file.

| − | *One of the error I the PBG was regarding retval which is an internal parameter in many functions. This was an error in PBG. Now resolved.
| |
| − | *Errors have majorily shrinked now by taking care of the above issues.
| |
| − | *Now the major errors are here http://tny.cz/2ed6eadc
| |
| − | *There are main two types of error left.
| |
| − | ##Accessing of symbols from union which is not supported by PBG.
| |
| − | ##Also overloading functions in string class of opennurbs.

| |
| − | *While Compiling I received many errors related to overloading of functions.
| |
| − | *I have seen that these are in ON_String and ON_wString class.
| |
| − | *These are mainly created due to excessive overloading of methods.
| |
| − | *I have removed some redundant overloaded functions from these classes and now these work.

| |
| − | *Since Union is not supported by PBG, therefore the generated file creates error issues while compiling.
| |
| − | *In OpenNurbs library there is an instance of union in a struct MAP_VALUE
| |
| − | *I have contacted the developer of PBG. They have suggested on mannually changing the generated c++ code.
| |
| − | *I have thus manually changed the c++ code wherever there are instances of the struct.
| |
| − | *And thus now the struct errors are eliminated.

| |
| − | *Now everything compiles perfectly.
| |
| − | *But on loading the compiled library in a python shell I lot of symbols are not defined.
| |
| − | *I found that BRL_CAD main repository removes the OpenGL dependencies thus I also removed them
| |
| − | *The problem on diagnosis turned out that, some functions in OpenNurbs have only declarations and lack definitions. This is indeed a common practice by c++ developers.
| |
| − | *But Since pybindgen only scans header files thus the undefined symbols creep in.
| |
| − | *I have removed such declarations. And it works well.
