tried compiling this module with ngnix getting above error

If i try CFLAGS="$CFLAGS -std=c99" getting error for u_char datatype

Please help me with this how to compile this module with Ngnix

Thank you for reporting this issue. Are you using the directions specified here: https://web.dev/how-to-set-up-signed-http-exchanges/#step-3-option-2? Also, which compiler version are you using to build? Thank you for providing answers to these questions.

Hi Thanks for replying to this issue

Yes I have followed the same steps given in https://web.dev/how-to-set-up-signed-http-exchanges/#step-3-option-2

Iam using gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-44) compiler

Thank you for providing this information. Do you have the exact error you are getting for u_char? It maybe that we might need to replace that usage to be C99 compliant. See: https://stackoverflow.com/questions/1918934/is-u-char-a-standard/1921519#1921519

An error like the above not only these there are more similar errors like this for u_char

If you need screenshot i will give you

This appears to be an issue with building an NGINX source. Have you tried: https://stackoverflow.com/questions/22667200/nginx-fails-to-make-with-submodule-os-x-10-9?

More specifically:

You can get it to compile by removing the -D_POSIX_C_SOURCE=200112L feature test macro in the config file under nginx-gridfs

Replace:

CFLAGS="$CFLAGS -Wno-unused-function -Wno-missing-field-initializers -D_POSIX_C_SOURCE=200112L --std=c99 -Isrc"
with:

CFLAGS="$CFLAGS -Wno-unused-function -Wno-missing-field-initializers --std=c99 -Isrc"

Nt able to locate line CFLAGS="$CFLAGS -Wno-unused-function -Wno-missing-field-initializers -D_POSIX_C_SOURCE=200112L --std=c99 -Isrc" in /nginx-sxg-module/config

tried adding line in /nginx-sxg-module/config but that dosent work

also tried adding a line in configure command for nginx still result is same.

Am I searching for the line in the wrong file???
Or some other options to change.

configure command for Nginx is
LDFLAGS="-L/usr/local/apps/libsxg/lib -L$AMPPS_PATH/lib -L$AMPPS_PATH/openssl-11/lib -lssl -lcrypto"
CPPFLAGS="-I$AMPPS_PATH/include -I$AMPPS_PATH/libsxg/include -I$AMPPS_PATH/openssl-11/include"
./configure
--prefix=$PATH_NGINX/etc
--sbin-path=$PATH_NGINX/sbin/nginx
--conf-path=$PATH_NGINX/etc/nginx.conf
--error-log-path=$PATH_NGINX/var/log/error.log
--http-log-path=$PATH_NGINX/var/log/access.log
--pid-path=$PATH_NGINX/var/run/nginx.pid
--lock-path=$PATH_NGINX/var/run/nginx.lock
--add-dynamic-module=$SRC_PATH/nginx-sxg-module
--with-ipv6 && make && make install >> $LOG 2>&1

tried this:
LDFLAGS="-L/usr/local/apps/libsxg/lib -L$AMPPS_PATH/lib -L$AMPPS_PATH/openssl-11/lib -lssl -lcrypto"
CPPFLAGS="-I$AMPPS_PATH/include -I$AMPPS_PATH/libsxg/include -I$AMPPS_PATH/openssl-11/include"
CFLAGS="$CFLAGS -Wno-unused-function -Wno-missing-field-initializers --std=c99 -Isrc" ./configure
--prefix=$PATH_NGINX/etc
--sbin-path=$PATH_NGINX/sbin/nginx
--conf-path=$PATH_NGINX/etc/nginx.conf
--error-log-path=$PATH_NGINX/var/log/error.log
--http-log-path=$PATH_NGINX/var/log/access.log
--pid-path=$PATH_NGINX/var/run/nginx.pid
--lock-path=$PATH_NGINX/var/run/nginx.lock
--add-dynamic-module=$SRC_PATH/nginx-sxg-module
--with-ipv6 && make && make install >> $LOG 2>&1

have lsxg and lssl on custom paths
