在 ubuntu 11.10 和 rails 3.1.0 上使用乘客安裝 nginx 模組安裝 nginx 時出錯

這是使用passenger-install-nginx-module (rvmsudo) 安裝nginx 的錯誤消息。nginx 是 1.0.6 安裝在 /opt/nginx 下（預設）。寶石安裝乘客之前成功。

/usr/bin/ld: /home/dtt/.rvm/gems/ruby-1.9.2-p290/gems/passenger-3.0.9/
ext/nginx/../common/libpassenger_common.a(aggregate.o): undefined
reference to symbol 'round@@GLIBC_2.2.5'
/usr/bin/ld: note: 'round@@GLIBC_2.2.5' is defined in DSO /usr/lib/gcc/
x86_64-linux-gnu/4.6.1/../../../x86_64-linux-gnu/libm.so so try adding
it to the linker command line
/usr/lib/gcc/x86_64-linux-gnu/4.6.1/../../../x86_64-linux-gnu/libm.so:

--------------------------------------------

It looks like something went wrong

hey! I solve this issue moving block:

ngx_feature="Math library" ngx_feature_name= ngx_feature_run=no
ngx_feature_incs="#include <math.h>" ngx_feature_path=
ngx_feature_libs="-lm" ngx_feature_test="pow(1, 2)"  . auto/feature if
[ $ngx_found = yes ]; then
    CORE_LIBS="$CORE_LIBS -lm" fi

to after:

ngx_addon_name=ngx_http_passenger_module HTTP_MODULES="$HTTP_MODULES
ngx_http_passenger_module" NGX_ADDON_SRCS="$NGX_ADDON_SRCS \
    ${ngx_addon_dir}/ngx_http_passenger_module.c \
    ${ngx_addon_dir}/Configuration.c \
    ${ngx_addon_dir}/ContentHandler.c \
    ${ngx_addon_dir}/StaticContentHandler.c" NGX_ADDON_DEPS="$NGX_ADDON_DEPS \   
    ${ngx_addon_dir}/Configuration.h \
    ${ngx_addon_dir}/ContentHandler.h \
    ${ngx_addon_dir}/StaticContentHandler.h \
    ${ngx_addon_dir}/ngx_http_passenger_module.h \
    ${ngx_addon_dir}/../common/Constants.h" CORE_LIBS="$CORE_LIBS  \
    ${ngx_addon_dir}/../common/libpassenger_common.a \
    ${ngx_addon_dir}/../common/libboost_oxt.a \
    -lstdc++ -lpthread"

in ext/nginx/config
