cmake认为变量是一个目录

Question

我正在尝试使用建议的cmake路径安装trilinos包。我没有任何使用cmake的经验，但我找到了一个示例bash脚本。当我尝试执行这个脚本时，我得到了错误

源目录"/home/USER/code/packages/trilinos_build/MPI_EXEC:FILEPATH=/usr/bin/pkg/mpiexec“不存在CMake错误。指定--help了解用法，或按CMake图形用户界面上的help按钮。

我检查了cmake文档，我非常确定语法是正确的，我遗漏了什么？

#!/bin/bash

# Set this to the root of your Trilinos source directory.
TRILINOS_PATH=../trilinos_source
TRILINOS_BUILD_PATH=./

#
# You can invoke this shell script with additional command-line
# arguments.  They will be passed directly to CMake.
#
EXTRA_ARGS=$@

#
# Each invocation of CMake caches the values of build options in a
# CMakeCache.txt file.  If you run CMake again without deleting the
# CMakeCache.txt file, CMake won't notice any build options that have
# changed, because it found their original values in the cache file.
# Deleting the CMakeCache.txt file before invoking CMake will insure
# that CMake learns about any build options you may have changed.
# Experience will teach you when you may omit this step.
#
rm -f CMakeCache.txt

#
# Enable all primary stable Trilinos packages.
#
cmake \
  -D CMAKE_INSTALL_PREFIX:FILEPATH="${TRILINOS_BUILD_PATH}/mpi" \
  -D CMAKE_BUILD_TYPE:STRING=RELEASE \
  -D Trilinos_ENABLE_TESTS:BOOL=OFF \
  -D Trilinos_ENABLE_ALL_PACKAGES:BOOL=OFF \
  -D TPL_ENABLE_MPI:BOOL=ON \
  -D MPI_EXEC:FILEPATH="/usr/bin/pkg/mpiexec" \


$EXTRA_ARGS \
$TRILINOS_PATH

我在cmake上也有类似的问题，这是因为最后一行和$EXTRA_ARGS \之间的空白输入。只需删除空行，错误就会消失。

所以你的文件应该是这样的：

#!/bin/bash

# Set this to the root of your Trilinos source directory.
TRILINOS_PATH=../trilinos_source
TRILINOS_BUILD_PATH=./

#
# You can invoke this shell script with additional command-line
# arguments.  They will be passed directly to CMake.
#
EXTRA_ARGS=$@

#
# Each invocation of CMake caches the values of build options in a
# CMakeCache.txt file.  If you run CMake again without deleting the
# CMakeCache.txt file, CMake won't notice any build options that have
# changed, because it found their original values in the cache file.
# Deleting the CMakeCache.txt file before invoking CMake will insure
# that CMake learns about any build options you may have changed.
# Experience will teach you when you may omit this step.
#
rm -f CMakeCache.txt

#
# Enable all primary stable Trilinos packages.
#
cmake \
  -D CMAKE_INSTALL_PREFIX:FILEPATH="${TRILINOS_BUILD_PATH}/mpi" \
  -D CMAKE_BUILD_TYPE:STRING=RELEASE \
  -D Trilinos_ENABLE_TESTS:BOOL=OFF \
  -D Trilinos_ENABLE_ALL_PACKAGES:BOOL=OFF \
  -D TPL_ENABLE_MPI:BOOL=ON \
  -D MPI_EXEC:FILEPATH="/usr/bin/pkg/mpiexec" \
$EXTRA_ARGS \
$TRILINOS_PATH

此外，如果在-D选项之间使用#注释任何行，也会显示相同的错误。在cmake\之后，所有行都必须是连续的。

希望这能有所帮助！
