TC议题:cmake macros改进总结
by wufengguang
23 Oct '24
23 Oct '24
# cmake macros改进,及其600+包升级 ## issues
https://gitee.com/src-openeuler/cmake/issues/I5OATI
## 使用cmake编译安装需要单独定义DESTDIR cmake install ./ ## 打包时会导致安装路径不明确,打包文件不完整,所以建议改为: DESTDIR="%{buildroot}" cmake --install ./
https://gitee.com/src-openeuler/cmake/pulls/31
**%cmake_build, %cmake_install 等相关宏的缺失, 使得从 rpm 生态的其他发行版移植软件包不便。** 部分Fedora中包,如asdcplib,SPEC文件中会使用%cmake3_build, %cmake3_install宏定义。 但是在openEuler中没有这几个定义,导致用户自行rpmbuild asdcplib.spec报错。
https://gitee.com/src-openeuler/cmake/pulls/53
由于相关宏的缺失,很多的确需要 out-of-source building 的包都会在 spec 中通过各种方式手动指定编译目录参数 Closed: 不完全兼容已有%cmake,会导致软件包批量构建失败aom等软件包批量失败。
https://gitee.com/src-openeuler/cmake/issues/IAND9Y
## cmake新增支持%cmake_build和%cmake_install的实施方案 经过多方讨论,提供如下兼容方案1 ## PRs ### 方案1 <

关于openEuler master分支默认使能 LTO 相关说明
by wangchunyang (F)
22 Oct '24
22 Oct '24
LTO(Link-Time Optimization)全称链接时优化,是一项将编译优化延后到链接时进行编译技术。该技术由于拥有链接时的全程序视角,相比于传统编译流程中的单文件编译优化,往往可以提供更多的优化机会,做出更激进的优化决策,带来更强的性能与更小的二进制体积。 我们已经在openEuler master分支上默认使能了这一编译优化。你可以在
https://gitee.com/src-openeuler/openEuler-rpm-config/pulls/242
找到相关合入。如果你想要关闭这一特性,可以在spec文件中添加 %define _lto_cflags %{nil} 以规避。 openEuler Compiler SIG 王淳洋
