How to build module ngx_http_opentelemetry_module for version nginx 1.20.1 #525
Description
I'm trying to figure out how to build ngx_http_opentelemetry_module for version nginx 1.20.1 in Centos 7 and is it possible?
From a container with Centos 7 in the downloaded archive nginx-1.20.1,
I execute:
-
[root@200e088735f3 nginx-1.20.1]#
./configure --add-module=/opt/src/1.0.1/opentelemetry-cpp-contrib-webserver-v1.0.1/instrumentation/otel-webserver-module/src/nginx/
where /opt/src/1.0.1/opentelemetry-cpp-contrib-webserver-v1.0.1/instrumentation/otel-webserver-module/src/nginx/
webserver/v1.0.1 and contains files,
Makefile
config
ngx_http_opentelemetry_log.c
ngx_http_opentelemetry_log.h
ngx_http_opentelemetry_module.c
ngx_http_opentelemetry_module.h -
Configure works fine, but at the make stage I get errors:
/opt/src/1.0.2/opentelemetry-cpp-contrib-webserver-v1.0.2/instrumentation/otel-webserver-module/src/nginx//ngx_http_opentelemetry_module.c:1511:12: note: expected 'const char *' but argument is of type 'u_char *'

req_payload->headers[count].value = (const char)(h->value).data;

How can I build ngx_http_opentelemetry_module for the required version of nginx server?
