安装pcl库时，有如下报错：

完整日志文件：
install.txt

此错误应该是libboost_filesystem-mt.a被编译成了32位

期待的结果

期望libboost_filessytem-mt.a编译成64位，并正确安装pcl库

工程配置

set_languages('cxx17')
add_includedirs('include') --添加本项目头文件搜索目录
add_includedirs('/usr/local/cuda/include') -- 否则会找到不到driver_types.h

add_requires("opencv","yaml-cpp",'fmt',"cxxopts","eigen",{system=false}) -- 不使用系统包

add_requires('pcl',{system=false,config={shared=true}}) -- pcl的包会添加boost部分模块的依赖


target('oilfield_common')
    set_kind('shared')
    add_files('common/*.cpp')
    add_packages("opencv",'yaml-cpp','cxxopts','boost')

附加信息和错误日志

执行xmake -vD
输出太长了，保存到下面的文件里了

上图第一个是我通过xmake require --extra="{config={shared=true},system=false}" boost安装的boost是动态库，且是64位。如下图

第二个是安装pcl时，xmake它自己又安装一次boost，编译出来的库是静态库。使用objdump -a libboost_filesystem-mt.a的输出

[xiaomi2077]

很奇怪啊，我把124文件夹里的静态库复制到5bc文件夹下，并将5bc目录名改为124。改名后的124(原5bc目录)如下图：

然后执行xmake编译项目，输出如下：

note: install or modify (m) these packages (pass -y to skip confirm)?
in xmake-repo:
  -> pcl 1.12.1 [shared:y]
please input: y (y/n/m)

这次找到了libboost_filesystem-mt.so.1.78.0动态库，但仍报错The following variants have been tried and rejected: *libboost_filesystem-mt.so.1.78.0 (32 bit, need 64)
这是把这个库识别成了32位，可是libboost_filesystem-mt.so.1.78.0通过file命令查看是64位啊：）

[waruqi]

那说明安装的库没问题咯，就是 64 的，是 cmake find 时候，内部调用了啥检测，检测成了 32bit? 那应该是 cmake 的问题吧。。要不你看下 cmake 相关 find package 怎么找的它

默认编译安装 boost ，一般肯定是 64 的。。如果你 host 是 64 的话，就是调用 gcc 默认编译，不会去额外设置修改 arch 的

[xiaomi2077]

@waruqi 找了一个小时。。。，大佬能再提示提示吗？我对cmake不太熟悉。

[waruqi]

可以 google 下相关错误，应该有不少类似的参考：

https://stackoverflow.com/questions/61145830/cmake-error-while-using-find-packageboost-in-cmakelists-txt-no-suitable

[xiaomi2077]

不知道为什么boost默认编译成32位的库了，解决方法是手动编译下在的boost源码，并安装。--address-model=64指定编译成64位。命令如下：
./bootstrap.sh
./b2 install --prefix=/home/ubuntu/.xmake/packages/b/boost/1.78.0/124a5e8540714d31b251349b7d7f3fd2 --with-filesystem --with-date_time --with-iostreams --with-system --address-model=64 --link=static
然后再使用xmake安装pcl就可以了。
但是安装的pcl不全，少了好多库，如下图，左边是xmake安装的，右边是自己安装的

我看仓库里好像只能安装vtk和cuda，不知道在哪里设置才能安装pcl的全部模块。。。

[waruqi]

包里有配置 --address-model=64 的，

https://github.com/xmake-io/xmake-repo/blob/a140c62bb87ff301f919b5dcc94f9f6a5c4455d1/packages/b/boost/xmake.lua#L147

而且我看你最早d的截图，里面编译出来也是 64 的。没啥问题

[xiaomi2077]

但是它报错是 libboost_filesystem-mt.a (32 bit, need 64)，意思是这个静态库是32位，需要64位的库。而且我也没改pcl和boost的cmake
我这个是aarch64平台，符合 if package:is_arch("x64", "x86_64") then的判断吗？（我不太懂这些架构归类关系

[waruqi]

提个 pr 过来到 dev branch， https://github.com/xmake-io/xmake-repo/blob/a140c62bb87ff301f919b5dcc94f9f6a5c4455d1/packages/b/boost/xmake.lua#L146

这里加个 arm64 的 arch

[xq114]

改成package:is_arch(".+64")这样更好吧？目前xmake支持的arch里面64位的都是以64结尾的

[waruqi]

也可以

[xq114]

我看仓库里好像只能安装vtk和cuda，不知道在哪里设置才能安装pcl的全部模块。。。

可以xmake -vD > log.txt看看cmake log，里面应该有为什么这些组件没有被编译

[waruqi]

boost 包里面，我加上 arm64 了，更新下仓库再试下，xrepo update-repo

[xiaomi2077]

@waruqi 不行，似乎.+64没有匹配到我的平台。还是报了不是64位的错误。我把boost包的xmake.lua的else分支从address-model=32修改为address-model=64就可以了

[waruqi]

你执行 xmake l os.arch 给我看下

[xiaomi2077]

[waruqi]

在更新下试试

[xiaomi2077]

好了，谢谢。但是为什么只生成这些库？不能全部的模块都生成吗？

[waruqi]

如果它还可以生成其他库，可以自己提 pr 改进下这个包。。https://github.com/xmake-io/xmake-repo/blob/master/packages/p/pcl/xmake.lua

目前 xmake-repo 仓库的包，都是用户根据自己需求，自己维护的。

[xiaomi2077]

好的，再次感谢

[xiaomi2077]

好了，谢谢。但是为什么只生成这些库？不能全部的模块都生成吗？

我知道为什么只生成这几个库了。
原因：pcl好多库都直接或间接依赖于flann。
https://github.com/xmake-io/xmake-repo/blob/6d323eab58f59d2c1142c1bd8bc20b7f9888a39f/packages/p/pcl/xmake.lua#L31 仓库里这一行把原来cmake的find_package(FLANN 1.9.1 REQUIRED)改为了find_package(flann CONFIG REQUIRED)。可能是CONFIG里没有配置好，不太懂cmake。
解决办法：把仓库里替换FLANN的哪一行注释掉就好了。不过要用xmake提前安装好flann1.9.1

[waruqi]

@xq114 这个帮忙看下？

[xq114]

不过要用xmake提前安装好flann1.9.1

你确定是用xmake安装的flann吗？xmake安装的flann pcl应该找不到才对，这里有cmake的详细log吗

[xiaomi2077]

不清楚了。我查了一下，xmake装了flann1.9.1,系统库里也找到了libflann 1.9.1。

这里有cmake的详细log吗

cmake日志在哪找？.xmake/cache 和.xmake/packages里都没有

[xq114]

那应该是用的系统库的flann。可以提供一下.xmake/packages/f/flann/.../1.9.1/cmake/flannConfig.cmake和.xmake/packages/f/flann/.../1.9.1/cmake/flannTargets-release.cmake的内容吗

改了，现在应该可以了
