Compile and Run C++ Application in Alpine Docker Container

Question

I've been provided the source code from an older project in c++ and need to compile and run it in a Docker container running Alpine Linux. I unfortunately don't have experience compiling in Linux or much with c++, with much google, I have tried to deploy a Docker container running Alpine Linux, install compile libraries/tools and try and compile using the make file, but I'm met with compile errors. I can't provide too much details about the source code as its company property, but I can provide the makefile and the steps I've been taking:

install compile tools in Alpine Linux:

apk update && apk add --no-cache autoconf build-base binutils cmake curl file gcc g++ git libgcc libtool linux-headers make musl-dev ninja tar unzip wget

makefile:

BIN := testExec

# relative paths to all project source files
SRCDIR := src
INCDIR := include
IDEDIR := ide_files

# files included in the tarball generated by 'make dist'
DISTFILES := $(BIN).a $(BIN).dll $(SRCDIR) $(INCDIR) $(IDEDIR)

# filename of the tar archive generated by 'make dist'
#DISTOUTPUT := $(BIN).tar.gz

# path to script that generates ctags files
CTAGS := $(dir $(abspath $(lastword $(MAKEFILE_LIST))))ctags.pl

# output files generated by ctags
CTAGS_FILES := .tags .tags_sorted_by_file

# add other macro defines by calling make with a USER_DEFINES argument
#  e.g. [ make USER_DEFINES='BLAH FOO="bar"' ] will add the string "-DBLAH -DFOO=bar" to your CFLAGS
UFLAGS   := $(addprefix -D,$(USER_DEFINES))
DFLAGS   := -DBUILD_DLL

# ensure the profiling flags get included for the compiler -and- the linker
CFLAGS   := $(DBGFLAGS) -Wall $(DFLAGS) $(UFLAGS) $(addprefix -I,$(INCDIR))
LDFLAGS  := $(DBGFLAGS) -shared -lm

# flags required for dependency generation; passed to compilers
DEPFLAGS    = -MT $@ -MD -MP -MF $(DEPDIR)/$*.Td

The makefile references i686-pc-mingw32-gcc so I've attempted to install the package that matches: https://pkgs.alpinelinux.org/contents?branch=edge&name=mingw-w64-gcc-base&arch=x86&repo=community For some reason I'm not getting the right files with the install though:

apk add mingw-w64-gcc-base --repository http://dl-cdn.alpinelinux.org/alpine/edge/community/

bash-5.1# apk info -L apk add mingw-w64-gcc-base | grep usr/bin
usr/bin/x86_64-w64-mingw32-cpp
usr/bin/x86_64-w64-mingw32-gcc
usr/bin/x86_64-w64-mingw32-gcc-11.2.0
usr/bin/x86_64-w64-mingw32-gcc-ar
usr/bin/x86_64-w64-mingw32-gcc-nm
usr/bin/x86_64-w64-mingw32-gcc-ranlib
usr/bin/x86_64-w64-mingw32-gcov
usr/bin/x86_64-w64-mingw32-gcov-dump
usr/bin/x86_64-w64-mingw32-gcov-tool
usr/bin/x86_64-w64-mingw32-lto-dump

So instead, I tried to install with the x86_64-w64-mingw32-gcc, modified the makefile:

#CROSS := i686-pc-mingw32-
CROSS := x86_64-w64-mingw32-

The source code folder structure is:

/SRC/ide_files
/SRC/include
/SRC/src

the make file is:

/SRC/ide_files/testApp/makefile

I then try:

make -f ide_files/testApp/makefile

It errors with:

x86_64-w64-mingw32-gcc -ggdb3 -feliminate-unused-debug-symbols -gno-strict-dwarf -shared -lm  -o testExec.dll -Wl,--out-implib,testExec.a <A lot of .o files>
