我要评论前言
本文为了记录自己在实习的过程中，学习到的有关occt开源项目的搭建工作，旨在教会小白从0开始下载开源项目及环境搭配，以及如何添加自定义测试内容，最终结果展示如下：
1、项目所需工具下载
本项目共需要使用四个工具，分别是occt开源代码，qt环境，cmake构建工具，vs2019，版本也会介绍。我会把cmake、vs2019、第三方库放到github链接里https://github.com/shadow0fiend/occt-project，occt源码以及qt环境需要自己下载
其中下载链接如下：
occt（7.8或7.6或7.5皆可）：download - open cascade technology
第三方库及vs2019：github - shadow0fiend/occt-project: 构建occt项目
qt工具（5.14.2）：index of /archive/qt
cmake（3.29.3）：download cmake
其中安装过程如下：
occt：下载64位的压缩包，解压到本地即可。
qt：对于新手，建议在勾选下载内容的时候全部选上（简单粗暴，不会缺少东西）
详情下载过程请参考链接：qt5.14.2安装、配置及测试（win10）-csdn博客
cmake：无脑下一步即可
详情下载过程请参考链接：windows下cmake安装步骤详解（图文）_windows终端安装cmake-csdn博客
安装完以后，本地应该有以下几个内容，注意检查cmake-gui、occt源码、编译用的三方库（下图product）、qt环境、vs2019
2、使用cmake编译源码
步骤1：在occt源码中建立一个build文件夹，用于存放编译后的文件
步骤2：打开cmake-gui，第一个位置填入occt源码文件夹的路径，第二个位置填入刚才创建好的build文件夹的路径
步骤3：点击configure，选择配置vs2019，x64，点击finish
步骤4：
第一步，在3rdparty_dir这一行，填入第三方库文件的路径，也就是product的路径。
第二步，然后勾选上build_samples_qt这一行。
第三步点击config。
步骤5：
第一步，修改qt路径，这个qt5.14.2是安装完qt以后的文件夹，自行在里面找对应的文件（如果没有找到，应该是qt安装下载的时候，有的选项没有勾上）
第二步，改完以后点击config，点击generate，点击open project
步骤7：cmake配置完毕，最终配置结果如下所示
3、配置项目运行环境
生成的项目如下所示（如果没有勾选qt，那么编译完成以后的项目是不包含samples文件的，只有非常简陋的可视化界面）：
步骤1：鼠标右击occtoverview，设置occtoverview为启动项。
步骤2：鼠标右击occtoverview，依次找到属性、debugging、environment，将以下内容粘贴进去，这是配置项目环境变量的。注意：需要将路径修改为自己电脑的路径。
配置解释：
casroot需要配置occt源码文件夹
csf_occt都是occt源码文件夹里面的文件
最后一行是配置qt的bin，qt的platforms，第三方库文件freetype，freeimage
casroot=e:\cpp\code\occt\occt-7_8_0
csf_fpe=0
csf_occtresourcepath=e:\cpp\code\occt\occt-7_8_0/src
csf_occtdatapath=e:\cpp\code\occt\occt-7_8_0/data
csf_occtsamplespath=e:\cpp\code\occt\occt-7_8_0/samples
csf_occttestspath=e:\cpp\code\occt\occt-7_8_0/tests
csf_occtdocpath=e:\cpp\code\occt\occt-7_8_0/doc
qt_debug_plugins=1
path=%path%;d:\qt\qt5.14.2\5.14.2\msvc2015_64\bin;d:\qt\qt5.14.2\5.14.2\msvc2015_64\plugins\platforms;e:\cpp\code\occt\products\freetype-2.5.5-vc14-64\bin;e:\cpp\code\occt\products\freeimage-3.17.0-vc14-64\bin;步骤3：复制 d:\qt\qt5.14.2\5.14.2\msvc2015_64\plugins 路径下的platforms文件，粘贴到 e:\cpp\code\occt\occt-7_8_0\build\win64\vc14\bind （生成的build文件里）路径下，如果要在release下运行，则将其粘贴到 e:\cpp\code\occt\occt-7_8_0\build\win64\vc14\bin路径下。
步骤4：编译运行即可完成。
4、如何自定义测试项目
先看自己修改的结果，在qt窗口自己添加按钮，用于触发函数，然后再在被触发的函数里编写自己的测试代码，就可以完成自定义测试了。
具体来说，需要修改5个地方：
找到occt源码里的samples文件（注意，不是build里的samples），进去以后找到occtoverview，再找到code文件夹。我的路径是：e:\cpp\code\occt\occt-7_8_0\samples\occtoverview\code
第一处修改：把自己写的cxx文件和.h文件放在这里（注意：直接在build里右键添加cxx文件是添加不到这里来的，因为那只是在build文件里添加了，而这是occt的源码文件，只能在这里添加以后，通过cmake编译进build才行）
具体的cxx和.h文件的写法参考如下，可以仿照源码的 topologysamples.cxx文件的写法，看我的cxx和topologysamples.cxx不同的地方即可，按照对应位置改就行。这里我附上我的源码。
#include "pengkaisamples.h"
void pengkaisamples::executesample(const tcollection_asciistring& thesamplename)
{
standard_boolean anissamplepresent = standard_true;
findsourcecode(thesamplename);
if (thesamplename == "firsttest")
firsttest();
else
{
myresult << "no function found: " << thesamplename;
mycode += tcollection_asciistring("no function found: ") + thesamplename;
anissamplepresent = standard_false;
}
myisprocessed = anissamplepresent;
}
void pengkaisamples::firsttest()
{
for (int i = 0; i < 20; i++)
{
std::cout << "enter firsttest" << std::endl;
}
}#ifndef pengkaisamples_h
#define pengkaisamples_h
#include "basesample.h"
#include <ais_interactivecontext.hxx>
//! implements pengkai samples
class pengkaisamples : public basesample
{
define_standard_rtti_inline(pengkaisamples, basesample)
public:
pengkaisamples(const tcollection_asciistring& thesamplesourcepath,
const handle(ais_interactivecontext)& thecontext)
: basesample(thesamplesourcepath, thecontext)
{}
protected:
virtual void executesample(const tcollection_asciistring& thesamplename) standard_override;
private:
// one function for every sample
void firsttest();
};
#endif //pengkaisamples_h第二处修改：添加xml文件
思路：仿照其他xml文件来写
<menu>
<menuitem name="pengkai">
<menuitem name="pengkai test">
<sample name="firsttest" function="firsttest"/>
</menuitem>
</menuitem>
</menu>第三处修改：
修改files文件，仿照其他人的写法，把cxx文件、xml文件和.h文件添加进去
adaptorcurve2d_ais.cxx
adaptorcurve2d_ais.h
adaptorcurve_ais.cxx
adaptorcurve_ais.h
adaptorpnt2d_ais.cxx
adaptorpnt2d_ais.h
adaptorvec_ais.cxx
adaptorvec_ais.h
basesample.cxx
basesample.h
dataexchange.xml
dataexchangesamples.cxx
dataexchangesamples.h
geometry.xml
geometrysamples.cxx
geometrysamples.h
makebottle.cxx
makebottle.h

tocaffunction_boxdriver.cxx

tocaffunction_cutdriver.cxx

tocaffunction_cyldriver.cxx

viewer2dsamples.cxx
viewer2dsamples.h
viewer3d.xml
viewer3dsamples.cxx
viewer3dsamples.h
pengkai.xml
pengkaisamples.cxx
pengkaisamples.h
第四处修改：
找到samples文件夹里的qt -> common -> src，找到这两个cxx文件，进去修改
仿照文件里topology结构的写法来写，把所有带有topology的地方全部换成自己修改的名字。
内容太多，这里不易说明，建议直接拿我修改后的代码与源码做对比，可以看出添加的部分在哪里

第五处修改：重新使用前面cmake编译的方法进行编译，重新生成build，运行以后就可以看到自己添加的按钮了，点击按钮即可触发测试函数，后续就可以自己在测试函数中编写测试案例
5、总结
注意好以下几个关键点：
1、环境和软件以及源码提前准备好
2、cmake编译的时候记得修改成自己文件路径所在位置
3、一般而言配置完以后运行成功就行，自定义测试需要修改的地方较多，不易操作
