Compile NGINX with full WebDAV support

For Developers
1

Dear all,

I am trying to install NGINX with full WebDAV support. The issue that I am facing is that NGINX from Master uses a very old version of the nginx-dav-ext-module (version 0.1), that misses support for the LOCK and UNLOCK functions, that are required by the Microsoft Windows WebDAV redirector. The current version 3.0 of the nginx-dav-ext-module has added that support and also switched from libexpat to libxml2.

I therefore updated the Makefile for NGINX with the new dependency and updated the nginx-dav-ext-module:

...
define Package/nginx/default
  SECTION:=net
  CATEGORY:=Network
  SUBMENU:=Web Servers/Proxies
  TITLE:=Nginx web server
  URL:=http://nginx.org/
  DEPENDS:=+NGINX_PCRE:libpcre +NGINX_SSL:libopenssl \
	+NGINX_HTTP_GZIP:zlib +NGINX_LUA:liblua +libpthread +NGINX_DAV:libxml2
endef
...
ifeq ($(CONFIG_NGINX_DAV),y)
  define Download/nginx-dav-ext-module
    #VERSION:=430fd774fe838a04f1a5defbf1dd571d42300cf9
    VERSION:=f5e30888a256136d9c550bf1ada77d6ea78a48af
    SUBDIR:=nginx-dav-ext-module
    FILE:=nginx-dav-ext-module-$$(VERSION).tar.gz
    URL:=https://github.com/arut/nginx-dav-ext-module.git
    #MIRROR_HASH:=0566053a8756423ecab455fd9d218cec1e017598fcbb3d6415a06f816851611e
    PROTO:=git
  endef
  $(eval $(call Download,nginx-dav-ext-module))

  define Prepare/nginx-dav-ext-module
	$(eval $(Download/nginx-dav-ext-module))
	gzip -dc $(DL_DIR)/$(FILE) | tar -C $(PKG_BUILD_DIR) $(TAR_OPTIONS)
  endef
endif
...

I have installed NGINX and all dependencies in the SDK and verified with make menuconfig that libxml2 is selected. When I compile, I can see that libxml2 is downloaded and compiled. However, I still get the following error message:

What can I do to solve this error? I have also installed the dev-version of these libary in Debian, but this did not help. Also installing libxslt in the SDK did not help either.

Any other ideas would be greatly appreciated!

I think you need to add the following to DEPENDS in Package/nginx/default.

+NGINX_DAV:libxslt

That's only true if the package libxslt exists already in the openwrt build system, but you said you added it to the SDK, so I assume this is true.

Hi @juppin,

Thank you for your input. I have already tried to include libxslt. I had the following variants in the Makefile:

+NGINX_DAV:libxslt +libxml2
or
+NGINX_DAV:libxml2 +libxslt
or
+NGINX_DAV:libxml2

all of them lead to the same error message that I have described above.

Any other ideas? Thank you!
