Is it possible to use --make when one or more of modules involved are split? I tried this with ghc 6.2.2 I do the following (doesn't work) Suppose we have syscall.hs and UNISTD_H.hs: the first contains Main and imports UNISTD_H, and the second is to be split. mkdir UNISTD_H_split ghc -c -split-objs UNISTD_H.hs ar cq libUNISTD_H.a UNISTD_H_split/*.o I get the library and the .hi file: no .o file ghc --make syscall.hs libUNISTD_H.a -o syscall It tries to recompile UNISTD_H.hs because there is no UNISTD_H.o, and links against the object file, not the library When I try ghc syscall.hs libUNISTD.a -o syscall it works, and only syscall.hs is recompiled, but I cannot use --make. I tried to name the library UNISTD_H.a, same result. Is it possible to get ghc recognize the library same way as if it were an object file (which corresponds to the interface file) and use --make? PS1 This is for that experiment with hsffig when the header file contains functions undefined in the default glibc. Linking against the library with split objs works fine, and executable size is much smaller, and unresolved references are gone. Only ability to use --make is missing here. PS2 It would be nice if the perl script splitting the assembler code also created the directory where the split object files go. Dimitry Golubovsky Middletown, CT
