我正在尝试安装gsl-2.5-https://www.gnu.org/software/gsl/。我已经使用了该命令sudo ./configure && make && make install，但仍然遇到权限问题：
libtool: link: ranlib .libs/libgsl.a
libtool: link: rm -fr .libs/libgsl.lax .libs/libgsl.lax
libtool: link: ( cd ".libs" && rm -f "libgsl.la" && ln -s "../libgsl.la" "libgsl.la" )
/bin/bash ./libtool --tag=CC --mode=link gcc -g -O2 -o gsl-randist gsl-randist.o libgsl.la cblas/libgslcblas.la -lm
libtool: link: gcc -g -O2 -o .libs/gsl-randist gsl-randist.o ./.libs/libgsl.so cblas/.libs/libgslcblas.so -lm
/bin/bash ./libtool --tag=CC --mode=link gcc -g -O2 -o gsl-histogram gsl-histogram.o libgsl.la cblas/libgslcblas.la -lm
libtool: link: gcc -g -O2 -o .libs/gsl-histogram gsl-histogram.o ./.libs/libgsl.so cblas/.libs/libgslcblas.so -lm

我猜测，由于某种原因，我的根权限不包括该 /usr/local/include目录。有谁知道为什么会出现这种情况以及我该如何解决它？
答案1
你的命令
sudo ./configure && make && make install
按顺序运行这三个命令：
sudo ./configure
make
make install
请注意，只有第一个具有 root 权限。
通常，您将作为您自己的用户帐户运行配置/制作阶段，仅为最终安装阶段分配 root 权限：
./configure
make
sudo make install
&&如果你有胆量，你可以加入这些。就我个人而言，我更喜欢将安装阶段作为一个单独的活动，只有当我很高兴前两个阶段不仅成功而且正确地完成时，我才应用它。
