# 构建机资源极小：本 COPR project 的该 chroot 未设置内存配额（API 实测
# memory_reqs=None，走默认 2048，即 2GB 内存），而 make 的并行度宏在该机
# 展开为 -j4（4 vCPU）。本包全部编译单元同属一个库目标，其中 robdef 生成的
# stubskel 源文件（com__robotraconteur__* stubskel.cpp）是单个数十万行的巨型
# 模板实例化单元，-j4 并发时多进程峰值内存叠加超过 2GB，被内核 OOM killer
# 杀掉编译器——build 112468 日志尾部：
#   c++: fatal error: Killed signal terminated program cc1plus
#   make[2]: *** [CMakeFiles/RobotRaconteurCompanion.dir/build.make:965:
#             CMakeFiles/RobotRaconteurCompanion.dir/robdef_gen/
#             com__robotraconteur__pointcloud__sensor_stubskel.cpp.o] Error 1
#   make[2]: *** Waiting for unfinished jobs....
# 同批次的 coal 包在同一构建机上出现同样症状，按同一手法修复后已构建成功
# （112469 -> 112473）。据此做两项调整：
# 1) 内存/耗时：configure 之后用 sed 把 -O1 -g0 追加到各目标 flags.make 的
#    CXX_FLAGS/C_FLAGS 行末尾。-O1 降低模板实例化与内联的内存/时间开销；-g0
#    关闭调试信息（spec 头部已关闭调试包，调试信息既不打包也无下游消费者）。
#    之所以在 shell 层追加，而不是给 configure 传带空格的引号参数：无法实证
#    rpm 宏会不会把该值按空格二次分词，一旦拆出独立参数 configure 会因未知
#    参数直接失败；而 GCC 取命令行最后一个 -O/-g 的语义保证行尾追加稳定生效。
# 2) 并行度：改为单线程构建。本包只有一个库目标，巨型 stubskel 与普通源文件
#    同属该目标、无法按目标拆分，故直接串行，保证任一时刻只有一个编译单元
#    驻留内存（-j2 反而最差：两个巨型单元位置相邻，正好同时驻留）。
#
# 本段注释一律不写百分号开头的宏名：RPM 会展开脚本体注释行里的宏，而多行展开的
# 宏第 2 行起会脱离注释变成真命令（coal 的 112470 即栽在这里）。
