I'm trying to build bcc bcc Alpine.
This is the Dockerfile I wrote to compile bcc:
FROM alpine:3.7
RUN apk add --update \
git \
llvm-dev \
llvm-static \
clang-dev \
clang-static \
cmake \
flex-dev \
bison \
luajit-dev \
build-base \
iperf \
linux-headers \
elfutils-dev \
zlib-dev \
python-dev
RUN ln -s /usr/lib/cmake/llvm5/ /usr/lib/cmake/llvm; \
ln -s /usr/include/llvm5/llvm-c/ /usr/include/llvm-c; \
ln -s /usr/include/llvm5/llvm/ /usr/include/llvm
RUN git clone https://github.com/iovisor/bcc.git
WORKDIR /bcc/build
RUN cmake .. -DCMAKE_INSTALL_PREFIX=/usr
Unfortunately, when running make I stumble upon the following error:
# make

How do I get around this issue?
Somewhat figured it out.
ino_t was not available in src/cc/ns_guard.h. I added include that defined ino_t:
#include <sys/types.h>
There were other obstacles in building bcc on Alpine though:
in file tests/cc/test_c_api.cc I had to comment out this section:
if (dlinfo(dlhdl, RTLD_DI_ORIGIN, &libpath) < 0) {
fprintf(stderr, "Unable to find origin of libz.so.1: %s\n", dlerror());
return -1;
}
because for some reason RTLD_DI_ORIGIN is not present in /usr/include/dlfcn.h:
cat /usr/include/dlfcn.h | grep RTLD_DI_ORIGIN
install a couple of missing packages (I updated original Dockerfile in question to have them included).
