【问题描述】:
我正在尝试在 Makefile 中使用 PGI 编译器的 -U__GNUG__ 标志,尝试编译文件夹中的所有 .cpp 文件,链接 Armadillo(使用 g++ 编译器,代码编译并运行。)Makefile我有如下:
CC=pgc++
CFLAGS= -U__GNUG__ -std=c++11 -fast -acc -Minfo=accel -larmadillo -lgsl -w
all:
${CC} ${CFLAGS} *.cpp -o cg
clean:
rm -Rf cg pgprof* *.o core
似乎可以编译对象文件,但无法编译最终的可执行文件。这个 Makefile 有什么问题?
编译代码使用:
~$ make
我收到以下错误:
cis.o: In function `arma::Col<double>::pod_type arma::op_norm::vec_norm_2<arma::Col<double> >(arma::Proxy<arma::Col<double> > const&, arma::arma_not_cx<arma::Col<double>::elem_type>::result const*)':

这应该通过包含标志 -U__GNUG__ 来解决。
任何建议将不胜感激。
【问题讨论】:
-
make 是否使用您希望它用来编译二进制文件的命令? (您没有在粘贴的输出中包含它。)
