使用 Cygwin 安装 C Umfpack 错误-Windows

Question

我正在学习 C，我想使用 Umfpack 库。我从这里下载了软件包 http://faculty.cse.tamu.edu/davis/suitesparse.html

我尝试使用 make 和 make -f Makefile 命令进行编译，但是出现了这些错误：

$ make -f Makefile
( cd Lib    ; C:/cygwin64/bin/make )
make[1]: Entering directory 'E:/SuiteSparse/UMFPACK/Lib'
cc    -O3 -fexceptions -fPIC -DNCHOLMOD  -I../Include -I../Source -I../../AMD/Include -I../../SuiteSparse_config -I../../CHOLMOD/Include -DDINT -c ../Source/umf_analyze.c -o umf_i_analyze.o
GNUmakefile:104: recipe for target 'umf_i_analyze.o' failed
process_begin: CreateProcess(C:\cygwin64\bin\cc, cc -O3 -fexceptions -fPIC -DNCHOLMOD -I../Include -I../Source -I../../AMD/Include -I../../SuiteSparse_config -I../../CHOLMOD/Include -DDINT -c ../Source/umf_analyze.c -o umf_i_analyze.o, ...) failed.
make (e=5): Access is denied.
make[1]: *** [umf_i_analyze.o] Error 5
make[1]: Leaving directory 'E:/SuiteSparse/UMFPACK/Lib'
Makefile:15: recipe for target 'all' failed
make: *** [all] Error 2

我花了很长时间在 google 上搜索解决方案，但我找不到任何解决方案。有人可以帮我解决这个问题吗？谢谢。

您是否阅读了 README 文件中子目录 UMFPACK 中的这些说明？

快速入门（Unix，或 Windows with Cygwin）：

To compile, test, and install both UMFPACK and AMD, the UMFPACK and AMD
directories must be in the same parent directory.  To configure, edit the
SuiteSparse_config/SuiteSparse_config.mk file (otherwise, you may get
warnings that the BLAS (dgemm, etc) are not found).  You may use
UMFPACK_CONFIG = -DNBLAS in the SuiteSparse_config/SuiteSparse_config.mk
file, to avoid using the BLAS, but UMFPACK will be slow.  Next, cd to this
directory (UMFPACK) and type "make".  To compile and run a FORTRAN demo
program for Harwell/Boeing matrices, type "make hb".  To compile a FORTRAN
main program that calls the 32-bit C-callable UMFPACK library, type "make
fortran".  When done, type "make clean" to remove unused *.o files (keeps
the compiled libraries and demo programs).  See the User Guide
(Doc/UserGuide.pdf), or ../SuiteSparse_config/SuiteSparse_config.mk for
more details (including options for compiling in 64-bit mode).

您是否遵循了这些说明？

您是否注意到，makefile 不会调用 E:\ 驱动器中的任何内容？
