我正在尝试在OpenSuse 42.1的MATLAB 2017a环境下使用GMT（通用地图工具）版本5.2.1。
kleanthis@leonidas:~> which gmt
/usr/bin/gmt
kleanthis@leonidas:~> gmt
GMT - The Generic Mapping Tools, Version 5.2.1 (r15220) [64-bit] [MP] [8 cores] (c) 1991-2015 Paul Wessel, Walter H. F. Smith, R. Scharroo, J. Luis, and F. Wobbe
Supported in part by the US National Science Foundation (http://www.nsf.gov/)
and volunteers from around the world (see http://gmt.soest.hawaii.edu/).

usage: gmt [options]
gmt <module name> [<module-options>]
options:
--help List a description of available GMT modules.
--show-bindir Show directory with GMT executables.
--show-cores Show number of available cores.
--show-datadir Show directory/ies with user data.
--show-modules Single list of all module names.
--show-plugindir Show directory for plug-ins.
--show-sharedir Show directory for shared GMT resources.
--version Print GMT version number.
if <module-options> is '=' we call exit (0) if module exist and non-zero
otherwise.
如您所见，gmt（命令）正在终端中运行。 在matlab环境中，我对gdal库有以下问题。有任何建议如何解决这个问题？
>> !ls %command ls working fine
esa_snap_installers giant pyaps TRAIN_3.beta_20171112 wraptext.m
>> !gmt
gmt: symbol lookup error: /usr/lib64/libgdal.so.20: undefined symbol:_ZN11xercesc_3_111InputSource11setEncodingEPKt
我检查了PATH是否与终端和matlab具有相同的值，我得到了相同的结果。

matlab中的LD_LIBRARY_PATH变量有一些额外的目录，但在这些目录中没有gdal的库。
