【问题】
在折腾makefile，写了个脚本用于实现自动编译docbook，用xsltproc+fop去生成pdf，期间遇到个很奇怪的，关于makefile无法赋值的问题。
如下方式：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 | #using toolsXSLT = xsltprocXSLT_FLAGS_COMMON = --xinclude #XSLT_FLAGS_FO = $(XSLT_FLAGS_COMMON) \# --stringparam callout.graphics $(CFG_CALLOUT_GRAPHICS) \# --stringparam admon.graphics $(CFG_FO_ADMON_GRAPHICS) \# --stringparam admon.graphics.path $(ADMON_GRAPHICS_PATH) \#XSLT_FLAGS_FO = $(XSLT_FLAGS_COMMON)# callout settingsXSLT_FLAGS_FO = --stringparam callout.graphics $(CFG_CALLOUT_GRAPHICS)ifeq ($(CFG_CALLOUT_GRAPHICS), 1)XSLT_FLAGS_FO += --stringparam callout.graphics.path $(CALLOUT_IMG_PATH_LOCAL)XSLT_FLAGS_FO += --stringparam callout.graphics.number.limit $(CALLOUT_NUM_LIMIT)endif# admon settingsXSLT_FLAGS_FO += --stringparam admon.graphics $(CFG_FO_ADMON_GRAPHICS)ifeq ($(CFG_FO_ADMON_GRAPHICS), 1)XSLT_FLAGS_FO += --stringparam admon.graphics.extension $(FO_ADMON_GRAPHICS_EXTENSION)XSLT_FLAGS_FO += --stringparam admon.graphics.path $(FO_ADMON_GRAPHICS_PATH_LOCAL)endifXSLT_FLAGS_FO += $(XSLT_FLAGS_COMMON)################################################################################# fo################################################################################$(OUTPUT_FILE_PO):$(MAIN_SRC_FILE) $(SUB_SRC_FILES) @echo "=============================== generating fo ==============================" export XML_CATALOG_FILES="$(XML_CATALOG_FILES)" && \ export XML_DEBUG_CATALOG=1 && \ $(XSLT) $(XSLT_FLAGS_FO) -o $@ $(XSL_NS_FILE_FO) $< |
是可以正常实现对于XSLT_FLAGS_FO变量的赋值的，对应的脚本执行结果中，–xinclude能通过XSLT_FLAGS_COMMON传递给XSLT_FLAGS_FO：
1 | xsltproc --stringparam callout.graphics 1 --stringparam callout.graphics.path D:/tmp/tmp_dev_root/cgwin/home/CLi/develop/docbook/config/images/system/callouts/ --stringparam callout.graphics.number.limit 30 --stringparam admon.graphics 1 --stringparam admon.graphics.extension .svg --stringparam admon.graphics.path D:/tmp/tmp_dev_root/cgwin/home/CLi/develop/docbook/config/images/system/colorsvg/ --xinclude -o ../output/fo/nand_get_type.fo docbook_fo_crl.xsl nand_get_type.xml |
但是对于按照正常逻辑，去这么写：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 | #using toolsXSLT = xsltprocXSLT_FLAGS_COMMON = --xinclude #XSLT_FLAGS_FO = $(XSLT_FLAGS_COMMON) \# --stringparam callout.graphics $(CFG_CALLOUT_GRAPHICS) \# --stringparam admon.graphics $(CFG_FO_ADMON_GRAPHICS) \# --stringparam admon.graphics.path $(ADMON_GRAPHICS_PATH) \XSLT_FLAGS_FO = $(XSLT_FLAGS_COMMON)# callout settingsXSLT_FLAGS_FO += --stringparam callout.graphics $(CFG_CALLOUT_GRAPHICS)ifeq ($(CFG_CALLOUT_GRAPHICS), 1)XSLT_FLAGS_FO += --stringparam callout.graphics.path $(CALLOUT_IMG_PATH_LOCAL)XSLT_FLAGS_FO += --stringparam callout.graphics.number.limit $(CALLOUT_NUM_LIMIT)endif# admon settingsXSLT_FLAGS_FO += --stringparam admon.graphics $(CFG_FO_ADMON_GRAPHICS)ifeq ($(CFG_FO_ADMON_GRAPHICS), 1)XSLT_FLAGS_FO += --stringparam admon.graphics.extension $(FO_ADMON_GRAPHICS_EXTENSION)XSLT_FLAGS_FO += --stringparam admon.graphics.path $(FO_ADMON_GRAPHICS_PATH_LOCAL)endif#XSLT_FLAGS_FO += $(XSLT_FLAGS_COMMON)################################################################################# fo################################################################################$(OUTPUT_FILE_PO):$(MAIN_SRC_FILE) $(SUB_SRC_FILES) @echo "=============================== generating fo ==============================" export XML_CATALOG_FILES="$(XML_CATALOG_FILES)" && \ export XML_DEBUG_CATALOG=1 && \ $(XSLT) $(XSLT_FLAGS_FO) -o $@ $(XSL_NS_FILE_FO) $< |
结果–xinclude就无法传递给XSLT_FLAGS_FO了，结果变成：
1 | xsltproc --stringparam callout.graphics 1 --stringparam callout.graphics.path D:/tmp/tmp_dev_root/cgwin/home/CLi/develop/docbook/config/images/system/callouts/ --stringparam callout.graphics.number.limit 30 --stringparam admon.graphics 1 --stringparam admon.graphics.extension .svg --stringparam admon.graphics.path D:/tmp/tmp_dev_root/cgwin/home/CLi/develop/docbook/config/images/system/colorsvg/ -o ../output/fo/nand_get_type.fo docbook_fo_crl.xsl nand_get_type.xml |
然后就导致之前就遇到过的错误：
1 | Element include in namespace 'http://www.w3.org/2001/XInclude' encountered in book, but no template matches. |
了。搞得很是无语。
【解决过程】
1.后来试了另外一种写法：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 | #using toolsXSLT = xsltprocXSLT_FLAGS_COMMON = --xinclude XSLT_FLAGS_FO = $(XSLT_FLAGS_COMMON) \ --stringparam callout.graphics $(CFG_CALLOUT_GRAPHICS) \ --stringparam admon.graphics $(CFG_FO_ADMON_GRAPHICS) \# --stringparam admon.graphics.path $(ADMON_GRAPHICS_PATH) \#XSLT_FLAGS_FO = $(XSLT_FLAGS_COMMON)# callout settings#XSLT_FLAGS_FO = --stringparam callout.graphics $(CFG_CALLOUT_GRAPHICS)ifeq ($(CFG_CALLOUT_GRAPHICS), 1)XSLT_FLAGS_FO += --stringparam callout.graphics.path $(CALLOUT_IMG_PATH_LOCAL)XSLT_FLAGS_FO += --stringparam callout.graphics.number.limit $(CALLOUT_NUM_LIMIT)endif# admon settings#XSLT_FLAGS_FO += --stringparam admon.graphics $(CFG_FO_ADMON_GRAPHICS)ifeq ($(CFG_FO_ADMON_GRAPHICS), 1)XSLT_FLAGS_FO += --stringparam admon.graphics.extension $(FO_ADMON_GRAPHICS_EXTENSION)XSLT_FLAGS_FO += --stringparam admon.graphics.path $(FO_ADMON_GRAPHICS_PATH_LOCAL)endif#XSLT_FLAGS_FO += $(XSLT_FLAGS_COMMON)################################################################################# fo################################################################################$(OUTPUT_FILE_PO):$(MAIN_SRC_FILE) $(SUB_SRC_FILES) @echo "=============================== generating fo ==============================" export XML_CATALOG_FILES="$(XML_CATALOG_FILES)" && \ export XML_DEBUG_CATALOG=1 && \ $(XSLT) $(XSLT_FLAGS_FO) -o $@ $(XSL_NS_FILE_FO) $< |
则也是可以正常地实现将–xinclude传递给XSLT_FLAGS_FO的：
1 | xsltproc --xinclude --stringparam callout.graphics 1 --stringparam admon.graphics 1 --stringparam callout.graphics.path D:/tmp/tmp_dev_root/cgwin/home/CLi/develop/docbook/config/images/system/callouts/ --stringparam callout.graphics.number.limit 30 --stringparam admon.graphics.extension .svg --stringparam admon.graphics.path D:/tmp/tmp_dev_root/cgwin/home/CLi/develop/docbook/config/images/system/colorsvg/ -o ../output/fo/nand_get_type.fo docbook_fo_crl.xsl nand_get_type.xml |
但是对于开始直接用：
XSLT_FLAGS_FO = $(XSLT_FLAGS_COMMON)
却无法实现参数赋值，还是没搞懂是啥原因。觉得很是诡异。不符合常理。
期待有高人指点指点。
