&gt;&gt;&nbsp;Hi&nbsp;All;

&gt;&gt;&nbsp;

&gt;&gt;&nbsp;No&nbsp;matter&nbsp;Linux&nbsp;or&nbsp;Windows,&nbsp;when&nbsp;try&nbsp;to&nbsp;build&nbsp;SHARED&nbsp;library,&nbsp;it&nbsp;will

&gt;&gt;&nbsp;always&nbsp;get&nbsp;the&nbsp;following&nbsp;error&nbsp;message.&nbsp;ADD_LIBRARY(hello&nbsp;SHARED&nbsp;&nbsp;hello.c)

&gt;&gt;&nbsp;

&gt;&gt;&nbsp;ADD_LIBRARY&nbsp;for&nbsp;library&nbsp;hello&nbsp;is&nbsp;used&nbsp;with&nbsp;the&nbsp;SHARED&nbsp;option,&nbsp;but&nbsp;the

&gt;&gt;&nbsp;target&nbsp;platform&nbsp;supports&nbsp;only&nbsp;STATIC&nbsp;libraries.&nbsp;Building&nbsp;it&nbsp;STATIC

&gt;&gt;&nbsp;instead.&nbsp;This&nbsp;may&nbsp;lead&nbsp;to&nbsp;problems.

&gt;&gt;&nbsp;

&gt;&gt;&nbsp;My&nbsp;question:

&gt;&gt;&nbsp;a)&nbsp;Why&nbsp;not&nbsp;support&nbsp;it?&nbsp;Is&nbsp;my&nbsp;CMakeLists&nbsp;any&nbsp;wrong&nbsp;for&nbsp;cross&nbsp;compiling?

&gt;&gt;&nbsp;b)&nbsp;Is&nbsp;there&nbsp;any&nbsp;method&nbsp;available&nbsp;to&nbsp;support&nbsp;it?

&gt;&gt;&nbsp;

&gt;&gt;&nbsp;I&nbsp;have&nbsp;searched&nbsp;in&nbsp;google&nbsp;and&nbsp;found&nbsp;the&nbsp;following&nbsp;threat,&nbsp;but&nbsp;after

&gt;&gt;&nbsp;SET_PROPERTY(GLOBAL&nbsp;PROPERTY&nbsp;TARGET_SUPPORTS_SHARED_LIBS&nbsp;TRUE),&nbsp;it&nbsp;still

&gt;&gt;&nbsp;got&nbsp;the&nbsp;same&nbsp;error&nbsp;message.

&gt;&gt;&nbsp;

&gt;&gt;&nbsp;Anyone&nbsp;who&nbsp;has&nbsp;idea&nbsp;about&nbsp;it&nbsp;please&nbsp;help,&nbsp;thanks.

&gt;&gt;&nbsp;

&gt;&gt;&nbsp;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&nbsp;&nbsp;brewmp-arm.cmake

&gt;&gt;&nbsp;

&gt;&gt;&nbsp;INCLUDE&nbsp;(CMakeForceCompiler)

&gt;

&gt;Are&nbsp;you&nbsp;sure&nbsp;you&nbsp;need&nbsp;this&nbsp;?

&gt;This&nbsp;is&nbsp;in&nbsp;general&nbsp;a&nbsp;bad&nbsp;idea.

&gt;

&gt;&gt;&nbsp;

&gt;&gt;&nbsp;SET&nbsp;(CMAKE_SYSTEM_NAME&nbsp;Generic)

&gt;

&gt;"Generic"&nbsp;operating&nbsp;system&nbsp;does&nbsp;not&nbsp;support&nbsp;shared&nbsp;libs.

&gt;Do&nbsp;you&nbsp;have&nbsp;an&nbsp;operation&nbsp;system&nbsp;on&nbsp;your&nbsp;target&nbsp;device&nbsp;?

&gt;

&gt;Alex
