代码从windows下visual studio到andriod平台迁移的修改记录

前言

前言也是迁言，从windows的visual studio 2012平台迁移到android平台上，需用修改挺多的代码和需用注意地方。

我们当然的平台当初就考虑了其他平台跨平台的应用问题，所以一开始在windows下就是用cmake来完成工程的建立的，cMakeLists.txt文件都做了一些处理，但是此时只是更针对或说首先保证windows下的编译和使用。

谨此做个记录。

1. modify cMakeLists.txt file,add android define and macro.

2.cmake ./../
	Build files have been written to: /home/andriod_a/build

3.size_t problem  add <cstddef> head file.

4.error: extra qualification 'rw::scoped_lock::' on member 'scoped_lock' [-fpermissive]
  remove the class identifier.

5. memcpy define in <string.h> .so change it.

6.no match for 'operator=' in 'inverse = rw_math::matrix3f::operator*(float) const((1.0e+0f / det))'

//inverse  = inverse * (1.0f/det);
	matrix3f temp = inverse * (1.0f/det);
	inverse = temp;

7.no match for 'operator=' in 'rot_mat = rw_math::matrix4f::make_rotation_matrix(
 matrix4f matrix4f_tmp = make_rotation_matrix(axis_,angle_in_rad_);
    rot_mat = matrix4f_tmp;

8.warning: inline function 'double const& rw_math::vector3d::operator[](int) const' used but never defined [enabled by default]

9.error: 'memcmp' was not declared in this scope
  #include <string.h>

10.initializing argument 2 of 'char* strncat(char*, char const*, size_t)' [-fpermissive]

11.compile jpeg library.
	copy source code,then write or change cMakeLists.txt,then create a buid file,open terminal in the new build file.
	cmake ./../ ,the last is make ,and it will show u.
12.multiple definition of 'std::__lg(int)
	i define the inline,so error.

13. the inline function which must achieve in head file ,and could not in *.cpp file. or,u can delete inline word in head files.

14.  conflicts with previous declaration 'typedef class rw::rw_shared_ptr<rw_json::json_value_iterator> rw_json::json_value_iterator::ptr'

	 multidefine .
15.no matching function for call to 'transform()
	transform(ext_.begin(), ext_.end(), ext_.begin(), ::tolower);

16. temp varity can't assign to non-const reference.
	rw_shared_ptr_shadow temp_shadow = entity_.to_shared_ptr_shadow();
	pt2model_entity_define::ptr temp_ptr = temp_shadow.to_shared_ptr<pt2model_entity_define>();
	build_pt2model_entity(_pGeometry,_pSymbol,temp_ptr);
17.	fatal error: json\json.h: No such file or director
		#include <json\json.h> ----->#include <json/json.h>
18.	fatal error: zlib\\zconf.h: No such file or directory
	----->#include "zlib/zlib.h"
19. error: cannot pass objects of non-trivially-copyable type 'const mapped_type {aka const struct std::basic_string<char>}' through '.
	--->(content_type_field).c_str();
20.537:49: error: invalid initialization of non-const reference of type 'std::string& {aka std::basic_string<char>&}' from an rvalue of type 'std::string {aka std::basic_string<char>}'
	string temp_str = request_.get()->get_url();
		string& tmp_req_url = temp_str;
21. error: no matching function for call
	temp variaty problem. make a temp variaty.
	matrix4d  temp_mat = world_mat * t_mat;
	render_system_->set_world_matrix(temp_mat);
22.	abs()--->fabs();

23.rw_terrian_manager.h:69:12: error: 'terrian_tile' was not declared in this scope
	can not recongize the friend class in GCC ,so chang forward declaration.
	#ifdef __linux__
	class terrian_tile;
	#endif
24. Windows.h: No such file or directory
		linux not compile this model,and commit it.
25.	itoa---->

	#include <sstream>
	std::ostringstream oss;
	std::string str = "";
	oss << _counter;
	str = oss.str();
26.	error: taking address of temporary
	box3d bbox = (instances_[i]->get_bounding());
	if (!manipulate_geo_hash(instances_[i]->get_id(), &bbox, update_geo_hash))
	ta
27.	error: no matching function for call to 'transform(std::basic_string<char>::iterator, std::basic_string<char>::iterator, std::basic_string<char>::iterator, <unresolved overloaded function type>)'
        transform(_texture_type.begin(), _texture_type.end(), _texture_type.begin(), ::tolower);

28.	GetModuleFileName((HINSTANCE)&__ImageBase,buffer,256);
		#include <stdio.h>
		------->string buffer = getcwd(NULL, 0);
		string execution_path= buffer;
29. xstring ----><string>

30.invalid cast of an rvalue expression of type 'rw::multi_point::ptr {aka rw::rw_shared_ptr<rw::multi_point>}' to type 'rw::multi_point*&'
		temp variable error.
31.	error: 'atof' was not declared in this scope
			std::stringstream oss;
			int temp_int;
			oss << _pri_string;
			oss >> temp_int;
			_var = temp_int;
32.error: conflicts with previous declaration
	u known, have more than one define in u's file.so,find and delete it.
33.	malloc no declear.
	#include <malloc.h>

34. 	image_info_->image_type = image_type_;
	  rw_image :image_type("ccccccccccccccccc"),

35. don't write like this.
			_runtime->register_service(_aaaa_multi_service_pid, get_aaa_multi_service());
			((_driver_multi_service_impl*)get_aaa_multi_service())->init(_runtime);
			((_driver_multi_service_impl*)get_aaa_multi_service())->set_runtime(_runtime);
36.	 register_service at last place when add_multi_service.
		((terrian_data_sqlite_service_impl*)tms)->init();
		_runtime->register_service(terrian_data_sqlite_service_pid, tms );

37.	dom does not show,because android  system does not support multi-therad rendering.
	so ,put the upload in draw thread.

38.please set RW_INDEX rw_uint16 in rw_render_object_creator.cpp when u compile the code in android system,otherwise leave it alone.	

非常感谢我的同事sun同学的帮助！
