openzwave-1.4.164 移植到MTK openwrt-3.10.14 遇到的一些坑

openzwave-1.4.164 移植到MTK openwrt-3.10.14 遇到的一些坑
一）wcsdup的编译错误

http://www.man7.org/linux/man-pages/man3/wcsdup.3.html

Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       wcsdup():
           Since glibc 2.10:
               _POSIX_C_SOURCE >= 200809L
           Before glibc 2.10:
               _GNU_SOURCE

【解决办法】
修改cpp\hidapi\libusb\hid.c，增加如下行
#define _GNU_SOURCE /* needed for wcsdup() before glibc 2.10 */

二）解决静态库编译问题

Creating vers.cpp
Building vers.o
Linking Static Library
mipsel-openwrt-linux-uclibc-ar: invalid option -- '/'
Usage: mipsel-openwrt-linux-uclibc-ar [emulation options] [-]{dmpqrstx}[
abcDfilMNoPsSTuvV] [member-name] [count] archive-file file...
       mipsel-openwrt-linux-uclibc-ar -M [<mri-script]
 commands:
  d            - delete file(s) from the archive
  m[ab]        - move file(s) in the archive
  p            - print file(s) found in the archive
  q[f]         - quick append file(s) to the archive
  r[ab][f][u]  - replace existing or insert new file(s) into the archive
  s            - act as ranlib
  t            - display contents of archive
  x[o]         - extract file(s) from the archive
 command specific modifiers:
  [a]          - put file(s) after [member-name]
  [b]          - put file(s) before [member-name] (same as [i])
  [D]          - use zero for timestamps and uids/gids

  [f]          - truncate inserted file names
  [P]          - use full path names when matching
  [o]          - preserve original dates
  [u]          - only replace files that are newer than current archive
contents
 generic modifiers:
  [c]          - do not warn if the library had to be created

  [S]          - do not build a symbol table
  [T]          - make a thin archive
  [v]          - be verbose
  [V]          - display the version number

【解决办法】
修改cpp\build\Makefile

 @echo "Linking Static Library"
# @$(AR) $@ $+
 @$(AR) cqs $@ $+
 @$(RANLIB) $@

三）解决编译动态库问题
Linking Shared Library
mipsel-openwrt-linux-uclibc-ld: unrecognized option '-Wl,-soname,libopenzwave.
so.1.4'
mipsel-openwrt-linux-uclibc-ld: use the --help option for usage information

【解决办法】
修改cpp\build\Makefile
#LDFLAGS += -shared -Wl,-soname,libopenzwave.so.$(VERSION)
LDFLAGS += -shared -soname libopenzwave.so.$(VERSION)

四）编译MinOZW时的问题
Linking /openwrt-3.10.14/build_dir/target-mipsel_24kec+dsp_uClibc-0.9.33.2/
openzwave/.lib/MinOZW
mipsel-openwrt-linux-uclibc-ld -L/openwrt-3.10.14/staging_dir/target-

mipsel-openwrt-linux-uclibc/bin/ld: final link failed: Bad value

【解决办法】
1）修改cpp\examples\MinOZW\Makefile
$(OBJDIR)/MinOZW: $(patsubst %.cpp,$(OBJDIR)/%.o,$(minozwsrc))
 @echo "Linking $(OBJDIR)/MinOZW"
# $(LD) $(LDFLAGS) $(TARCH) -o $@ $< $(LIBS) -pthread
 $(CXX) $(LDFLAGS) $(TARCH) -o $@ $< -ludev -lc -lpthread $(LIBS)

2）修改cpp\build\Makefile
编译libopenzwave.so 动态库时，添加上-lgcc_s -lc

else
#LDFLAGS += -shared -Wl,-soname,libopenzwave.so.$(VERSION)
LDFLAGS += -shared -fPIC -soname libopenzwave.so.$(VERSION)
LIBS  += -ludev -lgcc_s -lc
endif
CFLAGS  += $(CPPFLAGS)
