龙芯系统下，GTK与OPENGL共舞

龙芯操作系统下，GTK的版本是3.14，并不支持直接与OPENGL互操作。

查询了一些资料，在GtkDrawingArea上画出简单的OPENGL图形。

首先基于gtk的网站demo，链接如下：

https://wiki.gnome.org/Projects/Vala/OpenGLSamples

Using GLX: Coloured Triangle

原始vala代码如下：

usingGtk;usingGdk;usingGLX;usingGL;classGLXSample : Gtk.Window {privateX.Display xdisplay;privateGLX.Context context;privateXVisualInfo xvinfo;publicGLXSample () {this.title = "OpenGL with GLX";

        set_reallocate_redraws (true);

        destroy.connect (Gtk.main_quit);int[] attrlist ={

            GLX_RGBA,

            GLX_RED_SIZE,1,

            GLX_GREEN_SIZE,1,

            GLX_BLUE_SIZE,1,

            GLX_DOUBLEBUFFER,0};this.xdisplay =x11_get_default_xdisplay ();if (!glXQueryExtension (xdisplay, null, null)) {

            stderr.printf ("OpenGL not supported\n");

        }this.xvinfo =glXChooseVisual (xdisplay, x11_get_default_screen (), attrlist);if (xvinfo == null) {

            stderr.printf ("Error configuring OpenGL\n");

        }var drawing_area = newDrawingArea ();

        drawing_area.set_size_request (300, 300);

        drawing_area.set_double_buffered (false);this.context = glXCreateContext (xdisplay, xvinfo, null, true);



        drawing_area.configure_event.connect (on_configure_event);

        drawing_area.expose_event.connect (on_expose_event);



        add (drawing_area);

    }private bool on_configure_event (Widget widget, Gdk.EventConfigure event) {if (!glXMakeCurrent (xdisplay, x11_drawable_get_xid (widget.window), context))return false;



        glViewport (0, 0, (GLsizei) widget.allocation.width,

                          (GLsizei) widget.allocation.height);return true;

    }private bool on_expose_event (Widget widget, Gdk.EventExpose event) {if (!glXMakeCurrent (xdisplay, x11_drawable_get_xid (widget.window), context))return false;



        glClear (GL_COLOR_BUFFER_BIT);



        glBegin (GL_TRIANGLES);

            glIndexi (0);

            glColor3f (1.0f, 0.0f, 0.0f);

            glVertex2i (0, 1);

            glIndexi (0);

            glColor3f (0.0f, 1.0f, 0.0f);

            glVertex2i (-1, -1);

            glIndexi (0);

            glColor3f (0.0f, 0.0f, 1.0f);

            glVertex2i (1, -1);

        glEnd ();



        glXSwapBuffers (xdisplay, x11_drawable_get_xid (widget.window));return true;

    }

}void main (string[] args) {

    Gtk.init (refargs);var sample = newGLXSample ();

    sample.show_all ();



    Gtk.main ();

}

编译命令：

$ valac --pkg gtk+-2.0 --pkg gdk-x11-2.0 --pkg gl --pkg glx glx-sample.vala

　　从这儿看，基于的是gtk+-2.0，同时需要gl.vapi与glx.vapi，可以到

https://wiki.gnome.org/Projects/Vala/ExternalBindings

下去获取

在ubuntu 18.04编译时，有部分编译错误，修正后的vala代码（编译通过，并不能运行）

usingGtk;usingGdk;usingGLX;usingGL;classGLXSample : Gtk.Window {privateX.Display xdisplay;privateGLX.Context context;privateXVisualInfo xvinfo;publicGLXSample () {this.title = "OpenGL with GLX";

        set_reallocate_redraws (true);

        destroy.connect (Gtk.main_quit);int[] attrlist ={

            GLX_RGBA,

            GLX_RED_SIZE,1,

            GLX_GREEN_SIZE,1,

            GLX_BLUE_SIZE,1,

            GLX_DOUBLEBUFFER,0};this.xdisplay ;//＝ x11_get_default_xdisplay ();
        if (!glXQueryExtension (xdisplay, null, null)) {

            stderr.printf ("OpenGL not supported\n");

        }this.xvinfo =glXChooseVisual (xdisplay, x11_get_default_screen (), attrlist);if (xvinfo == null) {

            stderr.printf ("Error configuring OpenGL\n");

        }var drawing_area = newDrawingArea ();

        drawing_area.set_size_request (300, 300);

        drawing_area.set_double_buffered (false);this.context = glXCreateContext (xdisplay, xvinfo, null, true);



        drawing_area.configure_event.connect (on_configure_event);

        drawing_area.expose_event.connect (on_expose_event);



        add (drawing_area);

    }private bool on_configure_event (Widget widget, Gdk.EventConfigure event) {if (!glXMakeCurrent (xdisplay, x11_drawable_get_xid (widget.window), context))return false;



        glViewport (0, 0, (GLsizei) widget.allocation.width,

                          (GLsizei) widget.allocation.height);return true;

    }private bool on_expose_event (Widget widget, Gdk.EventExpose event) {if (!glXMakeCurrent (xdisplay, x11_drawable_get_xid (widget.window), context))return false;



        glClear (GL_COLOR_BUFFER_BIT);



        glBegin (GL_TRIANGLES);

            glIndexi (0);

            glColor3f (1.0f, 0.0f, 0.0f);

            glVertex2i (0, 1);

            glIndexi (0);

            glColor3f (0.0f, 1.0f, 0.0f);

            glVertex2i (-1, -1);

            glIndexi (0);

            glColor3f (0.0f, 0.0f, 1.0f);

            glVertex2i (1, -1);

        glEnd ();



        glXSwapBuffers (xdisplay, x11_drawable_get_xid (widget.window));return true;

    }

}void main (string[] args) {

    Gtk.init (refargs);var sample = newGLXSample ();

    sample.show_all ();



    Gtk.main ();

}

针对gtk+-3.0的编译链接命令需要修改为：

$ valac --pkg gtk+-3.0 --pkg gdk-x11-3.0 --pkg gl --pkg glx glx-sample.vala

相应的vala代码为：

usingGtk;usingGdk.X11;usingGdk;usingGLX;usingGL;classGLXSample : Gtk.Window {//private X.Display xdisplay;

        drawing_area.set_double_buffered (false);

        if (!glXMakeCurrent (gdk_display.get_xdisplay (), gdk_window.get_xid(), context))return false;

        glEnd ();



        glXSwapBuffers (gdk_display.get_xdisplay (), gdk_window.get_xid());//x11_drawable_get_xid (widget.window));

        return true;

    }

}void main (string[] args) {

    Gtk.init (refargs);var sample = newGLXSample ();

    sample.show_all ();



    Gtk.main ();

}

vala生成的代码中，基于opengl的会自动包含glew.h，狗屎，又不一定要用到，注释掉后的c代码

Linux应用程序自行开启Core Dump生成功能

很多Linux桌面系统默认不生成Core文件，此时的应用软件遇到Crash问题没有Core文件，就很难确定问题根因。

因此，在应用中开启程序的Core Dump功能，很有实际意义

实现这个功能分两步：

1.设置进程可以dump

    //set app dumpable
    prctl(PR_SET_DUMPABLE, 1);

2.设置rlimit_core的大小

    //set core size
    structrlimit rlimit_core;

    rlimit_core.rlim_cur=CORE_FILE_SIZE;

    rlimit_core.rlim_max=CORE_FILE_SIZE;

    setrlimit(RLIMIT_CORE,&rlimit_core);

头文件依赖有如下：

#include <sys/prctl.h>#include<sys/resource.h>

安卓so下，cmake编译系统，如何仅导出指定符号

作者: admin

安卓下的so，由于需要链接第三方lib库，导出符号时，总是会将第三方的符号也导出了。

根据LD链接，可以指定相应的version_script，简化的version_script为如下格式：

{

global:

XXXXXXXXXXX;YYYYYYYYYYYY;local:*;};

XXXXXXXXXXX与YYYYYYYYYYYY即需要导出的符号。
研究了一下，利用nm.exe与awk.exe，实现了在windows下交叉编译时，只导出指定符号

关键代码行：

add_custom_command(TARGET abcd PRE_LINK

            COMMAND ${ANDROID_NDK}/toolchains/aarch64-linux-android-4.9/prebuilt/windows-x86_64/bin/aarch64-linux-android-nm.exe -g "\$(abcd_OBJECTS)"  > ${CMAKE_CURRENT_BINARY_DIR}/cwCrypt_${ANDROID_ABI}.txt

            COMMAND ..\\..\\..\\..\\awk.exe \"BEGIN{print(\\"{\\nglobal\:\\")} / T /{print $$NF,\\"\;\\"} END {print(\\"local\:\*\;}\\\;\\")}\" ${CMAKE_CURRENT_BINARY_DIR}/abcd_${ANDROID_ABI}.txt > ${CMAKE_CURRENT_BINARY_DIR}/abcd_${ANDROID_ABI}.def
            COMMAND ${CMAKE_COMMAND} -E remove -f ${CMAKE_CURRENT_BINARY_DIR}/abcd_${ANDROID_ABI}.txt )

这儿的abcd，即将要链接出来的so文件，默认只导出编译abcd时指定的目标文件中的符号；

利用awk的/ T /过滤掉非导出的符号

这儿会生成一个abcd_armv8.txt及abcd_armv8.def

此命令后会删除txt文件，相应def文件则使用如下命令来删除

add_custom_command(TARGET abcd POST_BUILD COMMAND ${CMAKE_COMMAND} -E remove -f ${CMAKE_CURRENT_BINARY_DIR}/abcd_${ANDROID_ABI}.def)

使用相应的def文件可以有两种实现方式，如下：

#set(CMAKE_SHARED_LINKER_FLAGS "-Wl,--version-script,\"${CMAKE_CURRENT_BINARY_DIR}/abcd_${ANDROID_ABI}.def\" ${CMAKE_SHARED_LINKER_FLAGS}")

set_target_properties(abcd PROPERTIES LINK_FLAGS"-Wl,--version-script,\"${CMAKE_CURRENT_BINARY_DIR}/abcd_${ANDROID_ABI}.def\"")

如此后，编译出来的so文件，将只剩下编译库时中指定导出的符号，其余符号均会被隐藏为内部符号
