Editor to share with you how to compile ceph libs3, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to understand it!

1. Prompt that the dependent libxml2 library header file libxml/parser.h cannot be found.

Build/obj/util.do: Compiling dynamic object src/simplexml.c:27:27: error: libxml/parser.h: No such file or directory src/simplexml.c:48: error: expected'=', 'asm' or' _ attribute__' before 'saxGetEntity' cc1: warnings being treated as errors src/simplexml.c:56: error: type defaults to' int' in declaration of 'xmlChar' src/simplexml.c:56: error: expected' ',','or') 'before' * 'token src/simplexml.c:88: error: type defaults to' int' in declaration of 'xmlChar' src/simplexml.c:88: error: expected';',','or') 'before' * 'token src/simplexml.c:111: error: type defaults to' int' in declaration of 'xmlChar' src/simplexml.c:111: error: expected';',','or') 'before' * 'token build/obj/acl.o: Compiling object

Resolve the problem by installing xml2 through yum install

2. Prompt that the dependent libxml2 library header file libxml/parser.h does not have the correct compilation file.

Make [3]: Entering directory `/ var/lib/jenkins/jobs/nds/workspace/src/libs3' make [3]: * No rule to make target `libxml/parser.h', needed by `build/obj/simplexml.do'. Stop. Make [3]: Leaving directory `/ var/lib/jenkins/jobs/nds/workspace/src/libs3'

The solution is as follows:

a. Using the command grep xml2 libs3/GNUmakefile to check xml2 dependencies is as follows

LIBXML2_LIBS: = $(shell xml2-config-- libs)

LIBXML2_CFLAGS: = $(shell xml2-config-- cflags)

b. Running. / configure above will generate a small Shell script xml2-config, which will be installed as part of libxml2

Check the path / usr/bin/xml2-config generated by this machine. The cflags option in the file is as follows

-- cflags)

Echo-I ${includedir} / libxml2

c. Rerun ldconfig or similar tools to update the list of installed shared libraries

d. Recompile libs3 after the steps above, but it still doesn't work.

e. Make clean;make compilation is performed in src/libs3, which is initially interpreted as libs3 will not re-look for dependency packages during compilation.
