我想在我的系统中设置 LEDA 库。

我已经从以下链接下载了 LEDA 库

http://www.algorithmic-solutions.info/free/d5.php 

    Instruction given in read me file 2. Preparations --------------- Unpacking the LEDA distribution file LEDA---.tar.gz will create the LEDA root directory "LEDA---". You might want to rename it or move it to some different place. Let denote the final complete path name of the LEDA root directory. To install and use the Unix object code of LEDA you have to modify your environment as follows: a) LEDAROOT: Set the environment variable LEDAROOT to the LEDA root directory: csh/tcsh: setenv LEDAROOT sh/bash: LEDAROOT= export LEDAROOT b) Command Search Path: Include $LEDAROOT/Manual/cmd into your command search path (environment variable path (csh) or PATH (sh)) and call rehash (if required by your system). c) Shared Library: (for solaris, linux, irix, osf1) If you planning to use shared libraries include $LEDAROOT into the LD_LIBRARY_PATH search path. Then go to $LEDAROOT and type make shared. This will construct the shared libraries from the static libraries. Please note: Building the shared library is not supported on each platform. d) xlman and demos: Go to $LEDAROOT and type make xlman to compile and link LEDA's interactive manual reader xlman. Now you can start xlman for reading and printing manual pages, starting demo programs and browsing more release notes. 3. Compiling and linking application programs --------------------------------------------- a) Use the -I compiler flag to tell the compiler where to find the LEDA header files. CC (g++) -I$LEDAROOT/incl -c file.c b) Use the -L compiler flag to tell the compiler where to find the library (libleda.a/so) CC (g++) -L$LEDAROOT file.o -lleda -lX11 -lm If using windows on solaris systems you might have to link with the system socket library and the network services library as well: CC (g++) ... -lleda -lX11 -lsocket -lnsl -lm c) Compile and link simultaneously with CC (g++) -I$LEDAROOT/incl -L$LEDAROOT file.c -lleda -lX11 -lm You may want to ask your system adminstrator to install the header files and library in the system's default directories. Then you no longer have to specify header and library search paths on the compiler command line.

我按照这些说明操作，但我在命令中遇到错误

> make xlman error coredump@coredump-VPCCB15FG:~/Documents/LEDA$ make xlman make -C demo/xlman make: *** demo/xlman: No such file or directory. Stop. make: *** [xlman] Error 2

有人请帮我设置图书馆。

注意:对于 Leda 库的免费版本，您无需构建包即可使用该库。它根本行不通。

要使用该库，只需将其包含在您的编译行和链接器中即可。

如果您从 shell 编译(假设您使用的是 Linux)，请执行以下操作:

1. Set the env variable to the library folder e.g export LEDAROOT= /path/to/Leda
2. Set the LD_LIBRARY_PATH env variable e.g export LD_LIBRARY_PATH=$LEDAROOT

验证是否已设置此变量，然后您可以编译、链接和运行。你可以简单地做

CC (g++) -I$LEDAROOT/incl -L$LEDAROOT file.c -lleda -lX11 -lm

有了这个你就可以开始了。

如果您使用的是 IDE，只需将包含路径(即/path/to/leda)添加到您的项目设置中即可。

这就是您所要做的。 构建库不起作用。只需包含它
